摘　　要：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。By using the pulse Q switched dye laser as pump source, the laser operation at 1.064 μm with a new laser crystal, Nd 3+ doped NaY(WO 4) 2 (eg. Nd∶NYW) was demorstrated, pumped at 595 nm in the short wavelength absorption band. 1.08 mJ output energy at a pump energy of 24.2 mJ was obtained. The pump threshold energy is less than 5.0 mJ.
