Abstract

A 1.47 W 885 nm diode-pumped Nd:LGS laser at 1.06 μm 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 1.21 and 1.22 for tangential direction and sagittal direction are obtained, respectively.
