OPTICAL LASER RESONATOR Russian patent published in 2007 - IPC H01S3/08 

FIELD: quantum electronics, in particular, optical resonators of lasers, possible use during development of lasers of various types and with wide spectrum of output powers.

SUBSTANCE: device consists of a totally reflecting mirror and output mirror, active substance and two Porro prisms, positioned on flanges. Held on first flange are output mirror and totally reflecting mirror, and also first Porro prism. Optical axes of mirrors are perpendicular to supporting surface of flange, while flat totally reflecting mirror is mounted with possible adjustment. Antireflection transmitting surface of first prism is parallel to supporting surface of flange, while reversal edge is positioned at even distance from optical axes of mirrors. Held on second flange is another Porro prism, its antireflection transmitting surface is parallel to supporting surface of first flange. Reversal edge is perpendicular to corresponding edge of first prism and positioned at even distance from optical axes of mirrors and first prism. Active substance is positioned in front of output mirror and a diaphragm is mounted between them, positioned strictly relatively to first flange.

EFFECT: increased dynamic and static stability of spatial and angular position of output beam of laser radiation, making it possible to form laser of modular type.
