FIELD: pulsed solid state lasers; high-power nanosecond radiation pulse generation.
SUBSTANCE: proposed system has two solid state lasers using electrooptically Q-switched cavity and parametric light oscillators. There are master lasers and amplifiers. Two active elements of master lasers having polished side surface are placed in single-lamp light. Two active elements of amplifiers are placed in other single-lamp light. Each amplifier is connected in double-pass ring circuit. The latter has first polarizer, polarization plane 90 deg. shifter, active element, second polarizer, first rotary mirror, telescope, dual-beam refraction plate, and second rotary mirror, all arranged in tandem.
EFFECT: enhanced stability of radiation pulse parameters and operating reliability, reduced mass and size.
