摘　　要：本文综述了掺钕钨酸钾钆Ｎｄ３＋：ＫＧｄ（ＷＯ４）２晶体研制近况，介绍了其晶体结构，光谱特性。Ｎｄ：ＫＧＷ晶体具有掺杂浓度高、泵浦阀值低、激光转换效率高的特性；The new development and research on the Nd-doped Potassium gadolinium tungstate (Nd:KGW)laser crystals are summarized. This paper introduced crystal stracture, spectrum characteries. The 5at.% Nd-doped KGW crystal was found to have the highest laser extraction efficiency and the lower pumping threshold. Multiwavelength operation is obtained in Q-switched flashlamp pumped. A strong and broad absorption line that makes this laser medium an excellent candidate for efficient diode pumping without temperature control.
