Laser with two reflectors forming optical resonator - has both reflectors on common support opposite one laser medium face, with specified reflector axes

摘要

The common support (8) of the laser reflectors (3, 4) is mounted opposite a face of the laser medium (1). Their arrangement is such that one reflector (3) optical axis coincides with that of the laser medium (rod) while the other reflector (4) optical axis is offset to be parallel to the first axis. Opposite the other face of the laser medium is mounted between both reflector axes, a bridging triple mirror, or prism (5). The latter is at a distance from the respective laser medium face. Preferably the two reflectors abut the support surface. Thus the latter forms a reference for the reflexion planes of the reflectors. The support maybe a plate with two windows (6, 7).
