利用脉冲调Q染料激光对掺钕双钨酸钇钠晶体 (Nd∶NYW )的短波长吸收带 (5 95nm)进行抽运 ,实现了1.0 6 4 μm激光运转 ,在抽运能量 2 4 .2mJ时 ,获得的激光输出能量为 1.0 8mJ ,阈值抽运能量小于 5mJ。
The pulsed Q-switched laser was used to pump the short-wavelength absorption band (595nm) of neodymium-doped sodium yttrium tungstate yttrium crystal (Nd:NYW) to achieve 1.06 4 μm laser operation. At a pumping energy of 24.2 mJ , The laser output energy is 1.08mJ and the threshold pumping energy is less than 5mJ.
