Abstract:
We report a novel ultrabroadband high-energy femtosecond laser to be built in our laboratory. A 7-femtosecond pulse is firstly stretched by an eight-pass offner stretcher with a chirp rate 15 ps/nm, and then energy-amplified by a two-stage optical parametric chirped pulse amplification (OPCPA). The first stage as preamplification with three pieces of BBO crystals provides the majority of the energy gain. At the second stage, a YCOB crystal with the aperture of ~50 mm is used instead of the KDP crystal as the gain medium to ensure the shortest pulse. After the completion, the laser will deliver about 8 J with pulse duration of about 10 femtoseconds, which should be beneficial to the attosecond pulse generation and other ultrafast experiments.

Abstract:
For several decades development of methods for generating ultrashort pulses has been an independent urgent scientific and technical problem. There is a constant improvement both in the methods of such pulses receiving and in methods of their use. The aim of this work was to investigate the possibility of realizing the coordinated operation of two fundamentally different types of pump lasers for the femtosecond oscillator and amplifier based on one single-lamp laser head and to create on this basis a compact high-power femtosecond system with pulsed pumping and one power unit.The practical implementation of two types of pulsed lasers (nano- and picosecond ones operating, respectively, in Q-switch and modelock regime) on a single laser head with two active elements and one pump lamp is carried out. The required synchronization in time the pump pulse femtosecond amplifier formation and quasi-stationary region of generated pulses in the output radiation of a femtosecond Ti:sapphire is obtained.On this basis a compact, pulse pumped monoblock laser system has been developed that can generate femtosecond pulses with a duration of 50–150 fs with an energy up to 1 mJ and a high enough pulse repetition rate (up to 1 kHz which is determined by the type of laser head and pump unit used). In the developed laser system a compact scheme of a stretcher-compressor with a single common diffraction grating is used.Laser systems of this type characterized by a relatively low cost due to the use of a single power supply unit for simultaneous pumping of the amplifier and oscillator, as well as lower requirements for the quality of optical elements and usage conditions due to the pulse mode of operation, are quite practical and can be used both in scientific research in the field of ultra-high-speed kinetic spectroscopy and nonlinear optics, as well as in numerous technical applications, particular in the precision processing of materials, as optical simulators of the action of heavy charged particles in testing the radiation resistance of integrated circuits and electronic modules.

Abstract:
Allier de fortes puissances moyennes et crêtes donne accès à un champ applicatif très large pour un système laser ultrarapide. Une technique qui s’est avérée capable de satisfaire ces exigences est la combinaison cohérente de faisceaux (CBC). Elle permet de séparer spatialement les faisceaux avant l’amplification pour les recombiner ensuite d’une manière cohérente en un unique faisceau. Afin d’obtenir une recombinaison efficace, les propriétés spatiales et spectrales de tous les faisceaux doivent être parfaitement en accord.Pour des applications comme l’accélération de particules, le recours à plusieurs milliers de fibres doit être envisagé. Il est donc nécessaire d’étudier des architectures CBC fortement évolutives en termes de canaux amplificateurs.Le projet XCAN vise à une première démonstration d’un tel système en réalisant la combinaison cohérente de 61 fibres amplificatrices. Afin d’étudier les défis scientifiques et techniques d’une telle architecture, une version de taille réduite comprenant sept fibres a été mise en place.La conception et la réalisation de ce prototype sont le sujet de cette thèse.Dans un premier temps, des simulations ont été effectués afin d’estimer les désaccords tolérables entre les propriétés spatiales et spectrales des différents faisceaux.Basé sur ce travail de modélisation, un système laser de combinaison cohérente de sept fibres a été ensuite assemblé et caractérisé. Les résultats obtenus sont très prometteurs et montrent que notre architecture est bien adaptée pour accueillir les 61 fibres du démonstrateur final XCAN
Future applications of high power ultrafast laser systems require simultaneously high average and peak powers. A technique which has proved to be capable of meeting these demands is coherent beam combining (CBC).In this technique, the beam is spatially split prior to amplification, and coherently recombined in one single beam afterwards. In order to achieve an efficient recombination, the spatial and spectral properties of all beams need to be perfectly matched.For applications such as particle acceleration, the coherent combining of several thousands of fibers needs to be considered. It is thus necessary to investigate highly scalable CBC architectures.The XCAN project aims at a first demonstration of such a scalable setup by coherently combining 61 fiber amplifiers. In order to study the scientific and technical challenges of such a system, a downscaled version consisting of seven fibers has been implemented.The design and characterization of this prototype is the subject of this thesis.As a starting point, numerical simulations have been performed in order to estimate the maximum tolerable mismatches between the spatial and spectral properties of the beams.Based on this modeling work, a seven fiber CBC system has been assembled and characterized. The obtained results are very promising and imply that our setup is well suited for the accommodation of all 61 fibers of the final XCAN demonstrator

Full text
Abstract:
Using a tuneable femtosecond- and nanosecond laser system at room temperature, it was observed that by photo-irradiation in the infrared region, methane can be photo-excited to undergo the coupling reaction in which ethane and hydrogen is formed. In similar conditions, the addition of carbon dioxide results in the formation of carbon monoxide through the photoreduction of carbon dioxide by methane. Molecular modelling calculations were used to determine the photoabsorption wavelength needed for C-H bond activation of methane. Calculations showed that the 2v3 overtone at 1.67 pxn was ideal for excitation. Fourier transform infrared spectroscopy was used to analyze the samples after excitation. These results suggested that partial dehydrogenation of ethane to ethylene also occurred during the coupling reaction of methane while traces of methanol were found in the CH4/CO2 mixture after excitation. Although pleasing results were obtained with the nanosecond laser system, the femtosecond laser system proved more reliable and efficient.

Abstract:
A near infrared hybridly mode-locked dye laser system consisting of a femtosecond oscillator and a high repetition rate dye amplifier was designed and built. This system was then applied to the study of room temperature below-bandgap femtosecond switching and coherent pulse propagation in GaAs/GaAlAs multiple quantum well waveguides. The noise properties of the oscillator output were studied using radio frequency spectrum analysis techniques. Two distinct modes of operation were identified: The first is characterized by the shortest pulse duration and its real-time autocorrelation signal appears more strongly modulated. The second mode of operation, which exhibits a slightly longer pulse duration and a smoother real-time autocorrelation signal, is obtained for a relative cavity length detuning of ΔL = -0.7 μm. Unexpectedly, the second mode features larger pulse duration fluctuations than the first mode and self-pulsing, while the pulse repetition timing and pulse energy fluctuations were found to be similar in both cases, making the first mode preferable for use in time-resolved experiments. Femtosecond all-optical switching under off-resonance room temperature excitation was demonstrated in a passive GaAs/AlGaAs multiple quantum well directional coupler for the first time. The required phase mismatch originates from an ultrafast refractive index change caused by the optical Stark effect. The main obstacle regarding practical device applications is its low transmission (less than 10%). The use of electrically pumped semiconductor waveguides that provide gain promises to remove this disadvantage. Below-resonance, coherent pulse breakup in a room temperature semiconductor waveguide was observed for the first time. Numerical simulations of the coupled semiconductor Maxwell-Bloch equations show that the light-matter interaction can induce enough chirp through self-phase modulation during propagation in order to violate the initial adiabatic following regime and cause pulse breakup. This coherent effect is distinctly different from self-induced transparency, because it does not involve Rabi-oscillations at the start of propagation, from temporal solitons, because it does not require group velocity dispersion, and from self-steepening. However, it should be ubiquitous under off-resonance pulse propagation with a pulse duration less than the polarization dephasing time.

Ph.D.
This dissertation details an investigation into the use of laser pulses from a titanium:sapphire regenerative amplifier laser system to vaporize analytes in ambient air for mass spectral analysis. The laser system was modified to operate in one of two distinct modes. In femtosecond (fs) mode the laser produced 2.5 mJ, ~60 fs laser pulses centered at 800 nm. In nanosecond (ns) mode the laser produced 2.4 mJ, ~10 ns laser pulses centered at 800 nm. Using appropriate optical components the laser pulse energy was attenuated to achieve pulses varying from 0.15 mJ to 2.0 mJ. Laser pulses were used to vaporize liquid and solid samples on different substrates. The laser vaporized material was captured and ionized by an electrospray source and then detected via a mass spectrometer instrument. It was discovered that samples on glass substrate could be vaporized by fs laser pulses, but not by ns laser pulses. Samples on metal substrate were successfully vaporized by both fs and ns laser pulses. Low energy ns laser pulses were less efficient than fs laser pulses of the same energy for vaporizing off metal substrate. A comparison of vaporization from aluminum, copper and stainless steel substrates revealed limited vaporization from copper by ns laser pulses. The electrospray ionization (ESI) mass spectral response of wet and dry proteins on stainless steel was similar for both fs and ns laser pulses. Experiments to test the capabilities of ns laser electrospray mass spectrometry (ns-LEMS) revealed that sample vaporization was limited to analysis on metal surfaces. This dissertation details methods for femtosecond laser electrospray ionization (fs-LEMS) to be used to quantify non-covalent protein-ligand interactions. Hen egg white lysozyme (HEWL) and N,N’,N”-triacetylchitotriose (NAG3) interactions were quantified via dissociation constant (Kd) measurements. The Kd for HEWL and N,N’,N”,N”’-tetraacetylchitotetraose (NAG4) were also measured. This dissertation also reports a miniaturized flowing atmospheric pressure afterglow (micro-FAPA) for use as an alternative ionization source of fs-laser vaporized analytes. Loratadine pills were vaporized and reacted with the gas stream from the micro-FAPA source to generate ions which were then detected by a mass analyzer. The ions detected varied in distribution as a response to the distance the sample was vaporized from the ion source. Complexed samples were tested and molecular assignments were difficult due to the numerous pathways for ion formation. The use of an ion filter to decrease the energy imparted on sample molecules during the ionization process of the micro-FAPA is also reported.

Abstract:
A usinagem de estruturas micrométricas pode ser feita com pulsos laser de nano, pico ou fentossegundos. Destes, porém, somente os mais curtos podem resultar em uma interação não térmica com a matéria, o que evita a fusão, formação de rebarba e zona afetada pelo calor. Devido à sua baixa potência média, contudo, a sua utilização na produção em massa somente pode ser considerada em casos muito especiais, isto é, quando o processamento não-térmico é essencial. Este é o caso da usinagem de semicondutores, aços elétricos, produção de MEMS (sistemas micro eletro-mecânicos), de micro canais e diversos dispositivos médicos e biológicos. Assim, visando a produção destes tipos de estruturas, uma estação de trabalho foi construída com capacidade de controlar os principais parâmetros de processo necessários para uma usinagem micrométrica com laser de pulsos ultracurtos. Os principais problemas deste tipo de estação são o controle da fluência e do posicionamento do ponto focal. Assim, o controle do diâmetro do feixe (no foco) e da energia devem ser feitos com grande precisão. Além disso, o posicionamento do ponto focal com precisão micrométrica nos três eixos, também é de fundamental importância. O sistema construído neste trabalho apresenta soluções para estes problemas, utilizando diversos sensores e posicionadores controlados simultaneamente por um único programa. A estação de trabalho recebe um feixe vindo de um laser de pulsos ultracurtos localizado em outro laboratório, e manipula este feixe de maneira a focalizá-lo com precisão na superfície da amostra a ser usinada. Os principais parâmetros controlados dinamicamente são a energia, o número de pulsos e o posicionamento individual de cada um deles. A distribuição espacial da intensidade, a polarização e as vibrações também foram medidas e otimizadas. O sistema foi testado e aferido com medidas de limiar de ablação do silício, que é um material bastante estudado neste regime de operação laser. Os resultados, quando confrontados com a literatura, mostram a confiabilidade e a precisão do sistema. A automatização, além de aumentar esta precisão, também aumentou a rapidez na obtenção dos resultados. Medidas de limiar de ablação também foram realizadas para o metal molibdênio, levando a resultados ainda não vistos na literatura. Assim, de acordo com o objetivo inicial, o sistema foi desenvolvido e está pronto para utilização em estudos que levem à produção de estruturas micrométricas.
Machining of very small structures has been made with nano, pico and femtosecond pulsed lasers. Among then, only femtosecond lasers may result in nonthermal interaction with matter, avoiding melting, formation of slag and heat affected zone. Mass production with such lasers yet can only be considered in cases where nonthermal effects are of prime importance. This is the case in machining of semiconductors and electric steels, the production of MEMS, microchannels, and many medical and biological devices. Hence, a workstation for production of such kind of microstructures was built with the capability of controlling the main parameters necessary for the machining process. Control of the laser fluence and focus positioning are the main concern in this kind of processing. So, the control of the laser beam diameter (in the focus) and of the pulse energy must be very precise. Positioning of focal point with micrometric precision in the three axes is also fundamental. The system built in this work provides solutions for these problems incorporating several sensors and positioning stages simultaneously controlled by a single software. The workstation receives a laser beam coming from another laboratory and delivers it to the surface of the sample managing with precision the main process parameters. The system can dynamically control the energy, number of pulses and positioning for each individual laser spot. Besides, the spatial distribution of the laser intensity, polarization and vibrations were also measured and optimized. The system was tested and calibrated with threshold ablation measurement for silicon, which is well studied in this regime of laser operation. The results where compared with data found in the literature and attested the reliability and precision of the system. Besides the increase in precision, the automation also turned much faster the data acquisition. Threshold ablation for metallic molybdenum was also obtained and resulted in data not found in the literature yet. Concluding the initial goal, the workstation was developed and is ready to be used in studies that can lead to production of micrometric structures.

Abstract:
Recent advances in mode-locked solid-state lasers have resulted in pulses as short as 8.5 fs in the 800 nm region from Ti:sapphire oscillators [1]. Using similar techniques, sub-50 fs pulses [2-4] have been generated in another solid-state laser system, Cr:forsterite, which operates in the 1.2 to 1.3 μm range. We report here results from both a regeneratively-initiated and self-initiated, mode-locked Cr:YAG laser [5] which is tunable from 1.51 to 1.53 μm. One hundred and twenty femtsosecond, nearly transform-limited pulses have been generated with peak output powers of 45 kW. The stable, high peak power pulses and room temperature operation of this laser make it a very suitable alternative to the cumbersome, cryogenic mode-locked NaCl laser [6] commonly used in both narrow bandgap semiconductor and optical communications research.

Abstract:
In this paper, a novel PZT film patterning method by femtosecond laser is proposed. The method is different from traditional dry-etching and wet-etching technology. Femtosecond laser microfabrication technology has several advantages such as high resolution, no mask direct-writing and seldom-heating, etc. A two-layer (PZT thin film and substrate) heating and ablating threshold model is built and the relationship of PZT/Si two-layer system micro ablation morphology depending on laser pulse energy is constructed. From the model and experiment data, we obtain the suitable energy region to pattern PZT film freely without damage Si substrate. A 3μm resolution of PZT pattern is achieved in our experiment. In order to verify the fabrication available of this technology, several micro functional devices are successfully patterned by optimized femtosecond pulsed laser energy and their function are detected. The results prove that the PZT patterning quality is good.

Abstract:
High-repetition rate femtosecond pulses in the 200-nm spectral region are very interesting for dynamic studies of adsorbates on metal surfaces and are advantageous over using longer wavelengths with multiphoton processes or lower repetition rate amplifiers since the latter can cause surface damage. Generation of the fourth harmonic (FH) of mode-locked Ti:sapphire lasers seems at present to be the most straightforward method to create a high-repetition rate short pulse laser source near 200 nm. Previous experiments on frequency quadrupling resulted in average powers on the 10 mW level in the picosecond regime [1], but in the femtosecond regime only attempts near 205 nm have been reported where the output power levels were not sufficient for any temporal characterization. [2] Here we report for the first time to our knowledge efficient FH pulse generation in the femtosecond regime below 205 nm. The shortest wavelength achieved is 193.7 nm.
