英文摘要：

A 1.47 W 885 nm diode-pumped Nd： LGS laser at 1.06 t~m is demonstrated by using a high quality Nd~ LGS crystal. A corresponding optical-to-optical efficiency of 17.9 %, the maximum slope efficiency of 21.4 %, and a beam quality factor M2 of 1. 10 and 1. 12 for x direction and y direction are obtained, respectively. The experimental results show that Nd.＂ LGS is an excellent crystal for direct pumping.
