Paper Abstract

A novel structure of micro-laser device is presented in this paper. Nd:YVO4 crystal is used as laser active medium, which thickness is 2mm. The array LD at wave-length 809nm is used as a pump source. The optical isolator plays a role in the eliminating back reflection in this system. The output power of 1.44W at 1064nm has been obtained for pumping power of 3W. The total optical to optical conversion efficiency and slope efficiency are 48% and 51.8%, respectively. And power stability <2% has been observed.
