Laser structure with mirrors and solid state excitable medium - has coolant flowing through channels in case and through holes in mirrors

摘要

The laser case contains a concave mirror on whose central axis a stimulatable solid state medium and a rod-shaped light source are provided. Tightly sealed spaces (1, 2) are provided outside the case part surrounding the solid state medium (6). Each of them contains at least one resonator mirror (14, 18) and is optically limited by the exit surface (9, 15) of the medium (6). The space (2) is optically limited at its other end by an entry lens (16) of an optical system (17). Coolant is fed and evacuated through inlet (21) and outlet holes and through channels (22, 24) in the case and through holes (25, 26) in the mirror (5).
