摘要：

Overtone supersonic cw HF laser with power density of about 8 kW is developed. Efficiency of the laser relative to emission of the main tone is about 40%. Coefficient of active medium gain measured by the technique of calibrated losses is (5.5 divided by 7.8).10(-4) cm(-1). Designed wavelength-discriminating mirrors operated at power density of about 40 kW/cm(2) (90 kW/cm(2) in the maximum one-pulse regime). We suggest to use regenerative amplifying principle with application of ring conjugate resonator, having zero effective length, for design of adaptive laser-optical systems based on power lasers with very small gain.
