AbstractAbstract
[en] The performance of a single-frequency Ho:YAG laser with bow-tie cavity injected by different polarized seed lasers is studied both theoretically and experimentally. With vertically polarized (s-polarized) seeding, a 9.7 mJ single-frequency laser with a pulse width of 183 ns at the repetition rate of 252 Hz is obtained. With horizontally polarized (p-polarized) seeding, an 8.8 mJ single-frequency laser with a pulse width of 220 ns at the repetition rate of 252 Hz is obtained. The laser operating in p-polarized seeding mode performs better than the one operating in s-polarized seeding because of the stable relative center frequency of the pulses (0.9 MHz in 1 h). (letter)

AbstractAbstract
[en] Based on the model of a bipolarised laser, which takes into account real orientations of absorbing and emitting dipoles of active centres in the unit cell of an Nd : YAG single crystal, we have shown that the appearance of low-frequency relaxation oscillations requires the participation of both competing pump channels through linearly and circularly polarised dipole transitions.

AbstractAbstract
[en] Large neodymium doped glass laser systems are presently being built for nuclear fusion research. However, the power which can be generated by these systems is generally limited by self focusing in the laser glass. This study was undertaken to develop laser glasses with a minimum nonlinear refractive index which would allow the generation of higher powers in these laser systems. Various fluorophosphate glass forming systems were investigated in order to develop laser glasses with ''optimum'' properties (low n2, medium sigma, long tau, highly stable). In these fluorophosphate systems, the regions of glass formation were defined and glass composition-property correlation equations were derived which related the various properties (n/sub D/, n2, sigma, the Nd3+ peak lambda, Δlambda, effective Δlambda, sigma and tau radiative) to the glass composition. Specific glass compositions were developed which had nonlinear refractive indices of about 1/3 those of commercial silicate laser glasses but had comparable spectroscopic properties (i.e., sigma). These glasses were sufficiently stable to cast single pieces of glass weighing in excess of 50 lbs

AbstractAbstract
[en] In this paper, the second harmonic of Nd:YAG laser was used for the fabrication of microchannels (microholes) in polymethylmethacrylate. It was found that irradiation parameters as well as focusing lens focal length have significant effect on the geometry of the microchannels; while, the quality of the channels is dominantly affected by the focusing lens focal length. Our results also show that the maximum accessible depth is increased with sample movement in drilling direction at an appropriate velocity. (paper)

AbstractAbstract
[en] We report on the nonlinear optical characterization of a new amorphous composite based on Ge28Se60Sb12/PVA. Nonlinear optical characterization of these films was studied by the Z-scan technique using an Nd : YAG laser (532 nm, 7 ns, 10 Hz).The studies show that the material is highly nonlinear. The films show reverse saturable absorption, which makes it useful for optical limiting applications.
