摘　　要：本文报道了我所生长的掺钕钨酸钾钆（ＫＧＷ）晶体的脉冲激光特性．当用氙闪光灯泵浦时，尺寸为φ３．４ ｍｍ×２４ ｍｍ的ＫＧＷ激光棒，最大激光输出为每个脉冲３５８．４　ｍＪ，总效率为 １．７％，斜率效率为 ３．３％，波长为１．０６７μｍ．实验证明，ＫＧＷ是一种很有前途的小型激光器工作物质．This paper presents the pulse laser characteristics of neodymium doped potassium gadolinium tungstate (KGW) crystals grown in our institute. The maximum laser output of a KGW rod with dimensions of φ3.4 mm×24 mm was 358.4 mJ/pulse at wavelength l.067 μm, when it was pumped with a single xenon flashlamp. The overall and slope efficiencies are 1.7% and 3.3% respectively. It can be seen from this work that Nd:KGW crystal is a promising material for miniature lasers.
