DISC-SHAPED SOLID LASER

摘要

A disc-shaped solid laser includes an overlapping matrix (1) of semiconductor lasers, a laser resonance cavity with a disc-shaped laser crystal (6) and a laser resonance cavity output lens (8), and a jet impingement cooling system (10) for cooling the disc-shaped laser crystal (6). The overlapping matrix (1) of semiconductor lasers emits pump light. A pump beam collimator (2) collimates the pump light. The collimated pump light enters into a focus cavity which comprises two parabolic mirrors (4,5) placed in a conjugating manner, the disc-shaped laser crystal (6) and a correcting mirror (7), and is condensed onto the disc-shaped laser crystal (6) many times. The laser resonance cavity output lens (8) receives and outputs the laser beam. The laser has simple mechanical structure, and it is easy to manufacture and install. High-efficiency and high-power laser light output is realized.
