本文介绍了一种直接用液体对流冷却的Nd：YAG薄片激光振荡器。详细研究了不同流型和不同流量下的激光性能。微尺度涡旋的存在会导致激光器输出功率的降低和光束质量的恶化。17.1在最大抽运功率为54.8W时，获得了100 W的激光输出，光-光效率为31.2%，斜效率为37.5%。
A Nd:YAG thin disk laser oscillator convection-cooled directly by the liquid is demonstrated. Lasing performance at different flow patterns and different flow rates is studied in detail. Micro-scale eddies that appear at the disk edge can induce decrease of the output power and the degradation of beam quality. 17.1 W of output power is realized at the maximum pump power of 54.8 W, corresponding to the optical–optical efficiency of 31.2 %, and the slope efficiency of 37.5 %.
