Useful model relates to optoelectronics, in particular, to the devices for production of powerful laser radiation, modulated in time in high frequency range, and can be used in the field of nonlinear optics, of checking condition of environment with the help of lidars, for forming pulses with time multiplexing radio frequency and microwave Photonics, in modern communication lines, for spectral analysis and medicine. In distinct from known an optical system for producing powerful laser radiation, modulated in high frequency range, containing pulse-periodic source of laser radiation, stretcher as agent, used for converting optical radiation parameters, and interferometer, providing generation of difference frequency, besides stretcher is located along the optical axis of the system between pulse-periodic source of laser radiation and interferometer, in proposed system along the optical axis of the system after of interferometer is located, at least, one quickly acting widely bandpass optical amplifier, providing amplification of all spectral component modulated of laser pulse. In particular, in optical system as widely bandpass optical amplifier can be selected amplifier quantum and/or parametric type. ; Widely provided by strip method optical amplifier quantum type may be amplifier glass-based or crystals, alloyed with ions of rare-earth metals, or widely provided by strip method optical amplifier parametric type may be amplifier based on nonlinear crystals. As of interferometer in optical system used interferometer or interferometer Mach-Zehnder interferometers. Optical system for producing powerful laser radiation may be supplemented by quantum amplifier, located between stretcherom and inferferometrom. -Significant reduction of dependence of the power of the output modulated laser radiation from beam strength of elements stretchera and of interferometer, and provision controlling warp parameters of output modulated laser radiation. 5 3. u. 2 ., 1 dwg.
