综述了近年来棒状、盘片、光纤和热容等高平均功率全固态激光器的进展和国内近期的工作。围绕限制激光器输出平均功率提高和激光光束质量下降的热效应问题,比较了各类激光器的优缺点。总结了减小或补偿无用热不利影响的现有技术手段,指出减小激光器热效应可能的技术途径。
Current developments of high power laser diode-pumped solid-state lasers such as disk rod laser, disk/slab laser, fiber laser and heat-capacity laser at home and abroad are investigated. Focusing on the problem of thermal effects in solid-state lasers which limits the increment of the output average power and degrades the output beam quality, the advantages and disadvantages of kinds of lasers are compared. Current techniques to decrease or compensate for the effects of the useless heat are summarized, and the probable techniques to reduce the laser's thermal effects are pointed out.
