An experimental study was made of the characteristics of time-dependent stimulated Raman scattering in methane. The first-Stokes-component pulse formed from spontaneous noise was found to be displaced relative to the unconverted part of the pump puls

Measurements were made of the dependences of the stimulated Brillouin scattering (STBS) threshold and of the gain g (cm/MW) on the pressure of argon. The influence of the focusing geometry on the process of competition between STBS and optical breakd

Theoretical and experimental investigations were made of the feasibility of effective time compression of light pulses as a result of stimulated Brillouin scattering of a light beam in gases. An optimal focusing geometry and a specific excess above t

Multistage compression of YAG:Nd laser pulses of 5 nsec duration by stimulated Brillouin scattering in CCl4 and of the second harmonic of the compressed pulses by stimulated Raman backscattering in CH4 (at a pressure of 30 atm) was used to generate S

Numerical calculations were made of a resonant parametric interaction between the anti-Stokes component, the pump, and the first and second Stokes components of stimulated Raman scattering in a gas (four-wave model). A Raman converter utilizing hydro

The example of stimulated Raman backscattering of picosecond pulses in a CaCO3 crystal confirmed experimentally the principal estimates of the optimal conditions for pulse compression (shortening) in focused beams. The duration of the second harmonic

A new apodizing aperture based on a birefringent crystal plate is suggested. The calculated and experimentally determined transmission functions of such an aperture are given. These apertures can be used in laser systems to produce the required spati
