- Abstract
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 %.
