“…The capacity of the laser beam to conduct self-focusing can be estimated numerically with the breakup integral, also called B-Integral and was found to be a useful criterion for designing laser amplifiers against beam instability. [18][19][20] It is given by the equation…”

A laser damage test facility delivering pulses from 100 fs to 3 ps and designed to operate at 1030 nm is presented. The different details of its implementation and performances are given. The originality of this system relies the online damage detection system based on Nomarski microscopy and the use of a non-conventional energy detection method based on the utilization of a cooled CCD that offers the possibility to obtain the laser induced damage threshold (LIDT) with high accuracy. Applications of this instrument to study thin films under laser irradiation are presented. Particularly the deterministic behavior of the sub-picosecond damage is investigated in the case of fused silica and oxide films. It is demonstrated that the transition of 0-1 damage probability is very sharp and the LIDT is perfectly deterministic at few hundreds of femtoseconds. The damage process in dielectric materials being the results of electronic processes, specific information such as the material bandgap is needed for the interpretation of results and applications of scaling laws. A review of the different approaches for the estimation of the absorption gap of optical dielectric coatings is conducted and the results given by the different methods are compared and discussed. The LIDT and gap of several oxide materials are then measured with the presented instrument: Al(2)O(3), Nb(2)O(5), HfO(2), SiO(2), Ta(2)O(5), and ZrO(2). The obtained relation between the LIDT and gap at 1030 nm confirms the linear evolution of the threshold with the bandgap that exists at 800 nm, and our work expands the number of tested materials.

“…Phosphate glasses have been studied for more than 100 years ago as such glasses can find applications in a variety of industrial applications, such as high power laser, medical , nuclear waste hosts, hermetic seals, and solid state electrolytes, just to cite a few applications. The applications of phosphate glasses are clear, so a better understanding of the response properties of phosphate glasses to irradiation could lead to further applications or improved glass compositions.…”

Glass and its properties are subject to a variety of changes under the influence of high energy radiation. Therefore, radiation-induced defects in glasses requires high attention due to the wide application of glasses in optics on board space craft, in image guides for reactor inspection, in optical fiber waveguide and in mobilization of high level radioactive waste, for example . In this paper, we present a mini review on radiation effects on phosphate glasses. We review the influence of various irradiation sources on the response of phosphate glasses, focusing on the advances over the past decades.

“…1 (the plates are not shown in the figure). Analysis of circular polarization is interesting in that nonlinear phase incursion for it is 1.5 times less than for linear polarization [16,22,27], hence, it is frequently used in high peak power lasers [14,[27][28][29].…”

A system of differential equations describing, neglecting diffraction, the propagation of laser radiation in a medium with birefringence and cubic nonlinearity is derived. It is shown that the efficiency of depolarization compensation by means of a 90° polarization rotator or a Faraday mirror decreases with increasing В-integral (nonlinear phase incursion). Comparison of the considered method effectiveness in the case of incident linear and circular polarization showed that for the circular polarization the optimal angle of polarization rotator is different from 90° and the degree of polarization is less than for the linear one.
