New experimental data were obtained on the laser damage of the surfaces of transparent dielectrics. It was found that illumination with high-power light pulses of 10–8–10–7 sec duration caused surfaces to emit primarily positive ions. The depen

The initial stage of laser-radiation-induced damage to the surface of transparent dielectrics was investigated by electron microscopy and by a study of the disturbed specular reflection under prebreakdown conditions. The deformation of the surface wa

An investigation was made of the photocurrent which appeared on the surface of a transparent dielectric subjected to laser illumination whose energy density was several times lower than the threshold value necessary for the generation of a spark. Fat

It is shown that premature damage of lenses and prisms can be avoided by suitable selection of the lens parameters and by optimal positioning of the prisms in a light beam. In this way, these optical elements can be made to work at higher flux densit

A close correlation was found between the quality of polishing of a transparent dielectric (K8 class), optical damage threshold, and photoelectric emission caused by high-power neodymium laser radiation. Measurements were made of the photoelectric em
