Correctness of z-scan measurements of nonlinear refractive indices for optical media is considered. It is shown that accuracy of these measurements is greatly affected by the thickness of the nonlinear medium layer (as compared with the diffraction l

Criteria for the laser damage in transparent solids are compared for different mechanisms of radiation absorption. It is shown that the most efficient mechanism of laser damage in a broad range of pulse durations (from millisecond to femtosecond lase

We propose a new method of temporal shaping of picosecond laser pulses using interference of chirped beams reflected from chirped volume Bragg gratings. This method is numerically simulated and experimentally tested. Quasi-rectangular picosecond puls
