流体直接冷却薄片型固体激光介质是美国通用原子公司“液体激光器”方案的核心思想,是固体激光实现十万瓦级高功率输出的有效途径。固液表面损耗、液体流场影响以及腔体附加损耗等,是此类激光器所面临的新问题。2012年5月中旬,清华大学的流体直接冷却固体激光器进行了首次整机实验,实现了激光输出。近日,该激 The direct cooling of sheet-type solid-state laser medium is the core idea of ​​the “General Purpose Liquid Crystal Laser” scheme of the U.S.A. It is an effective way for the solid-state laser to achieve a high power output of 100,000 watts. Solid-liquid surface loss, the influence of the liquid flow field and cavity additional loss, etc., are the new problems that such lasers face. In the middle of May, 2012, Tsinghua University conducted the first complete experiment of the fluid-cooled solid-state laser and realized the laser output. Recently, the shock
