Abstract:

Pico and femtosecond lasers present a growing interest for industrials applications such as surface structuring [1] or thin film selective ablation [2]. Indeed, they combine the unique capacity to process any type of material (dielectrics, semiconductors, metals) with an outstanding precision and a reduced affected zone. We report on results about surface engraving of metals (Al, Cu, Mo, Ni), semiconductor (Si) and polymer (PC) using a picosecond thin disk Yb:YAG-amplifier. The pulse duration of this source can be changed using two different configurations: direct amplification of a 34ps-oscil

Abstract:

Optical measurement techniques can address certain important challenges associated with nuclear safety and security. Detection of uranium over long distances presents one such challenge that is difficult to realize with traditional ionizing radiation detection, but may benefit from the use of techniques based on intense femtosecond laser pulses. When a high-power laser pulse propagates in air, it experiences collapse and confinement into filaments over an extended distance even without external focusing. In our experiments, we varied the initial pulse chirp to optimize the emission signal from

Abstract:

Significant oscillations of the spectral distribution of the idler pulses in the optical parametric amplification of chirped laser pulse have been observed experimentally. On the base of the obtained simple analytical solution we have showed that such oscillations and an asymmetry of the spectral and temporal distributions of the intensities of the signal and the idler were caused by small variations in the parameters of the initial idler in comparison with the signal one.

AbstractThis paper deals with the analytical study of the effect of chirping of a laser pulse on its intensity profile, as it propagates in plasma. Considering a matched laser beam, graphical analysis of the intensity distribution across the chirped laser pulse and growth of modulation instability has been presented. Further, considering finite pulse effects to be a perturbation, the growth rate of modulation instability of the chirped laser pulse is evaluated and compared with that obtained due to an unchirped pulse.

Abstract:

An equation is put forward to calculate the temporal diffraction intensity distribution of a chirped femtosecond laser pulse when it incites a circle aperture. In the aperture central direction an analytic expression is given to calculate the temporal intensity distribution. Many factors such as the width of the laser pulse, the radius of the circle aperture, the Fresnel number at central frequency, time and the chirped coefficient of the laser pulse affect the temporal intensity. Number calculation shows that if the width of laser pulse is within a few tens of femtoseconds and Fresnel number

Abstract:

Generation of large amplitude plasma waves using high-power lasers in either the wakefield or beat-wave scheme is considered. We show how the nonlinear behavior of the plasma wave may make it advantageous to split the total energy into more than one pulse in the wavefield scheme. When a beat wave is generated by a pulse of finite length, we show how the final wave amplitude may be enhanced if the frequency of one or both pulses is chirped in such a way that the wavelength of the beat increases from the front to the back of the pulse.

We present a theoretical study of the excitation of a charged quantum linear oscillator by chirped laser pulse with the use of probability of the process throughout the pulse action. We focus on the case of the excitation of the oscillator from the ground state without relaxation. Calculations were made for an arbitrary value of the electric field strength by utilizing the exact expression for the excitation probability. The dependence of the excitation probability on the pulse parameters was analyzed both numerically and by using analytical formulas.

Abstract:

In this paper, propagation of a linearly chirped laser pulse in air was investigated to control the remote ionization distance, numerically. Laser spot size and pulse length will be obtained versus effective initial parameters such as positive and negative initial chirp. It is seen that the initial chirp parameter and primary curvature of wave front have important role in focal distance variation and remote ionization. It was also shown that the group velocity dispersion (GVD) could alter and split the positively chirped laser pulse profile after nonlinear self-focusing.

The fundamental physical mechanism responsible for the self-focussing, filamentation, supercontinuum generation and conical emission of a powerful ultrashort laser pulse in a transparent optical medium is reviewed. The propagation can be described by the model of moving focus modified by the defocussing effect of the self-induced plasma through multiphoton interaction with the medium. Spatial and temporal self-phase modulation in both the neutral Kerr medium and the plasma transform the pulse into a chirped (elongated) and strongly deformed pulse both temporally and spatially.
