HOMOGENIZED ROD BASED MULTI-PUMP DISC SOLID-STATE LASER

摘要

A disc solid-state laser comprises two parabolic reflectors (3, 4) placed coaxially in a conjugated manner. The center of the first parabolic reflector (3) is arranged with a laser disk crystal (6) forming a specific angle with the optical axis of the first parabolic reflector (3). The laser disk crystal (6) adheres to a cooling finger (5). The center of the second parabolic reflector (4) is arranged with a homogenized rod (7). Pump light emitted by a semiconductor laser stacked array (1) is collimated by a pump light collimator (2), then enters a condenser chamber between the two parabolic reflectors (3, 4), and converge on the laser disk crystal (6) after being reflected multiple times by the two parabolic reflectors (3, 4), the laser disk crystal (6), and the homogenized rod (7). A laser beam generated by the laser disk crystal (6) by absorbing the pump light is output by a resonant cavity output lens (8). The disc solid-state laser of the present invention homogenizes the pump light spot while realizing high-efficient pumping, has lower requirements on the shaping and homogenization of incident pump light, has a simple system structure, is easy to be manufactured and assembled, and can efficiently output a high power laser beam of high quality.
