Full textWe have realized and demonstrated three efficients atom optics elements: a guide and a beamsplitter which use the dipole force and a concave mirror which uses the magnetic force. These elements have been tested with a cold atoms 87-Rb cloud at a temperature of 10 mK in an optical molasses. The guide is realized with a far red-detuned Nd:YAG laser beam which creates a 2-D dipole trap. When the atomic cloud is released from the optical molasses, it falls due to gravity and due to the dipole guide the atoms remain localised inside the guiding laser beam. The guide efficiency is about 40% over a distance of 30 cm. Furthermore, as the laser beam is focused an adiabatic compression of the cloud occurs, and in a defocusing region of the laser beam, its adiabatic cooling is observed to 2 mK, corresponding to a factor 5 between the temperature of the cloud in the molasses [1]. The results are numerically interpreted, by using a Monte Carlo statistic method. We have observed in the guide experiment and have demonstrated by calcu1ation that if the atoms enter in the guide with a kinetic moment and if the guide is pulsed, we generate a doughnut clouds. The beamsplitter uses two crossing dipole guides: one is along the vertical axis et the other along an oblique direction making a 0. 12 radian angle with the vertical. The atoms are first guided in the vertical one. When they have travelled a few millimeters the second guide is suddenly switched on. The created coupling at the crossing point of the two guides allows an atom transfer from the vertical to the oblique direction. The observation, 10 mm below the initial trap position, shows a cloud splitting ranging a few millimeters. The measured transfer efficiency is about 30% [2]. We have demonstrated numerically that time control of the switching time of the oblique guide could permit to increase a larger beamsplitter efficiency. The concave mirror uses a pulsed magnetic quadrupole field, applied when the atoms are fallen a few millimeters. We have clearly observed two bounces. The magnetic potential is curved and the atoms bounce and simultaneously are refocused [3]. Nevertheless, this mirror is not perfect and presents some aberrations. We have shown by using a Monte Carlo statistic method that an addition time orbiting magnetic field would significant1y reduce the aberrations of the mirror. [1] L. Provost, D. Marescaux, O.

Full textThe topic of this work deals with the realization of atom optic elements. We have developed and studied three elements: a dipole guide, a dipole beam-splitter and a magnetic concave mirror. These elements have been analysed by studying their influence on a 87Rb cold atoms cloud in propagation due to gravity. Cold atoms are produced in a magneto-optical trap. The atomic guide uses the dipole force created by a far red-detuned, vertically directed, TEM_00 laser beam. The dipole interaction leads to a potential well with finite depth, which transversally confine a large part of the atoms during their propagation. The guiding atoms do not expand due to their temperature. We have guided 15% of the atoms over a 30 cm distance. The beam-splitter uses the dipole force created by two crossed dipole guides, the first one along the vertical direction and the second one along an oblique direction at an angle of 0. 12 rad from the vertical. The atoms are first guided by the vertical guide along a 4 mm distance. Then the oblique guide is switched on. In the overlap region of the two crossing guides, the initial cloud is split. At the beam-splitter output, we obtain two clouds separated from about 1 mm. The splitter efficiency is about 40%. The magnetic concave mirror uses the Stern and Gerlach effect. After a 2 mm fall in the gravity field, the atoms are submitted to a magnetic field gradient created by two coils in the anti-Helmholtz configuration. This magnetic field induces cloud bounces because it creates a potential well in which the cloud oscillates and undergoes transverse focalisations. We have observed two bounces and multiple focalisations

In the past, a concave grating system of incident light is limited due to its narrow acceptance angle. If the acceptance angle becomes large, there will be a lot of energy out of concave grating. In order to collect energy, we designed a concave mirror. By adding a concave mirror, we are able to increase the light acceptance angle. Under the same condition of the resolution, the study shows the light intensity such a concave system with mirror as compared to a single concave system, and then compared the light intensity of the two systems with waveguide. Finally, the study choose a concave system with mirror and waveguide. We study the effects of the distance of ideal focal line and different detector sizes on the resolution and the light efficiency.

This paper presents an adjustable micro-concave mirror and its application on bio-detection system. The bio-detection system consists of the adjustable micro-concave mirror, a micro flow cytometer chip, and an optical detection module. The adjustable micro-concave mirror could be fabricated with ease using commercially available MEMS foundry service (such as multiusers MEMS processes, MUMPs). The thermal effect of micromachined bilayer micro-concave mirrors was first investigated. A finite-element model has been established to analyze such a deformation. Postprocessing temperature and curvature reveal a close relationship. As postprocessing temperature increases, the curvature of the micro-concave mirror increases, resulting in a larger out-of-plane deformation of the micro-concave mirror. The proposed adjustable micro-concave mirror has the potential to be widely used for micro-optics or biophotonic applications.

In this thesis, passive mode locking of diode-pumped Nd:YVO4 lasers are investigated by placing a semiconductor saturable absorber mirror (SAM) in a plano-concave cavity. By using the SAM with 2 % absorbance, the laser is able to generate continuous wave mode-locked pulses with average output power of 240 mW, repetition rate of 369 MHz, and duration of 11 ps under absorbed pump power of 1.3 W. When the SAM with absorbance of 0.5 % and 1 % was used, the lasers could only operate at Q-switched mode locked state. The peak power as high as 1.3 kW and 617.4 W is achieved for the SAM with absorbance of 0.5 % and 1 %, respectively. Our scheme with a long cavity is also demonstrated in terms of a five elements resonator.

This thesis investigates passive mode-locking of Nd: YVO4 lasers by using the semiconductor saturable absorber mirror (SESAM) and a plano-concave cavity. Two kinds of laser crystals are used. One is a thin Nd: YVO4 (1 mm in thickness) crystal and another is thick one (4 mm in thickness). For the thin laser crystal, there are two states of output which are characterized in multiple-pulse and single-pulse operations. At small tilt angle of laser crystal, multiple-pulse continuous wave mode-locked output is observed with the repetition rate of 500 MHz, pulse width of 4 ps, and output power of 230 mW under pump power of 780mW. By increasing the tilt angle, single-pulse continuous wave mode-locked output can be obtained with the pulse width of 9.2 ps and output power of 205mW at the same conditions as multiple-pulse case. For the thick Nd: YVO4 crystal, single-pulse continuous wave mode-locked output can be obtained with cavity lengths between 80 cm and 5 cm corresponding to the repetition rates between 185 MHz and 2.5 GHz. The pulse width obtained is between 8.5 ps and 14.7 ps.

In this dissertation, two kinds of concave micro-mirrors are designed. The off-axis micro-mirror is designed based on ray tracing for the fabrication on silicon substrate using e-beam writer and inductively coupled plasma. The aspect ratios of the surface relief of the diffractive micro-lenses and the micro-mirrors are compared to reduce the fabrication difficulty for the identical optical function. The results show that compared with the micro-lenses in SiO2 and GaN, the micro-mirrors are preferred to be fabricated than micro-lenses if their numerical apertures are lower than 0.6 and 0.2, respectively. Free space echelle grating is designed for Dense Wavelength Division Multiplexing (DWDM) system. It is based on the law of Rowland. It is a hybrid of a concave micro-mirror and blazed gratings. The design of the concave micro-mirror can be carried out on silicon substrate using e-beam writer and plasma etching .The blazed grating can be achieved by fine V-groove etching. We also demonstrate a novel method to mount micro-opto-electronic devices on a Si bench. Inductively Coupled Plasma ( ICP ) and KOH etching and are performed for carrying out this novel method. The Si-based component after through wafer etching was picked by the optical fibers and placed on the optical bench. This can not only make X, Y, Z, θ and the tilt directions precisely controlled but also be suitable for all components mounting on the optical bench.
