FIELD: laser engineering.
SUBSTANCE: optical scheme of laser head contains partially transparent parallel-plate mirror, two end reflectors, active and electro-optical elements, polarizer and nonlinear components. End reflectors are 90°-angled reflecting prisms. First reflecting prism is placed on the one side of active element and its vertex edge lies in vertical plane. Second reflecting prism is placed with polarizer, electro-optical element on the other side of active element. Its vertex edge lies in horizontal plane, and nonfunctional end surface lies in vertical plane passing through geometrical axis of active element.
EFFECT: production of laser with stable output parameters in case of laser head deformations and thermal wedge in active element.
