The characteristics of XeF and XeCl lasers stabilized by an external low-power ionizer were considered. Two laser operating regimes were investigated, one with a buildup of negative ions and the other with a discharge stabilized by an external low-po

The book describes modern methods of receiving laser signals, viz., by interferometry, by nonlinear optics, by laser amplification, and by heterodyne mixing. The theory of these methods is considered as applied to the problem of laser radars. Investi

An estimate is obtained of the time of appearance of optical breakdown in air near a rough surface of a solid. The various stages of breakdown are considered: heating of surface irregularities to the evaporation temperature, equilibrium heating of th

A model is proposed for the reflection of coherent light by a rough surface and it includes a correction needed to allow for the polarization on reflection. This model is employed to investigate the spatial characteristics of radiation in the diffrac

The temporal characteristics of Q-switched laser pulses are considered. The dependences are given of the duration (Δτ) and shape of pulses from solid-state lasers, operating in the giant-pulse regime, on the active-medium and resonator parameters,

It is argued that there is a need for an All-Union standard which would include scientifically based maximum permissible levels of irradiation of individual organs and of human body as a whole. The standard should also provide a unified classificatio

Calculations are made of the frequencies of transitions in the 01'1-[11'0, 03'0] "hot" band of the 12C18O2 molecule. These data are used in a theoretical analysis of the stimulated emission spectrum of an atmospheric-pressure 12C18O2 laser. It is fou
