摘要
介绍了适合高光束质量高平均功率的薄片型DPL原理,给出了设计原则并进行了实验.激光介质采用Nd:YAG,厚1 mm,增益区面积5 mm×7 mm,Nd掺杂浓度1.4%.用自行研制的CW1 kW铜微通道冷却二维阵列二极管激光抽运源,在20%占空比Q-CW抽运下,获得397 W输出,光-光转换效率39.3%.
Abstract
The principle of high-brightness and high-average-power thin-disk laser is introduced and the design principle is put forward. The experiment is carried out with Nd:YAG of 1 mm thickness and 1.4% Nd doping pumped by home-made CW 1 kW 2D-stacks diode array. The pump gain area is 5 mm×7 mm. The peak output power of 397 W is achieved with 39.3% optical to optical efficiency at 20% duty cycle Q-CW running mode.
