FIELD: laser engineering. SUBSTANCE: proposed solid-state laser is capable of lasing in two wavelengths and can be used to produce high-power laser emission pulses in close infrared range including that safe for human eyes. Laser has two cavities with common output mirror and one active element, as well as total emission distortion (TED) effect Q-switch. Disposed along path of beam reflected from TED Q- switch are polarizer, electrooptic element, and final element of cavity for λн emission wavelength. Arranged along path of forward beam are two mirrors blind for λс emission wavelength and transparent for λн one. EFFECT: enhanced directivity of emission. 1 cl, 1 dwg
