High Efficiency Laser Crystal NdSFAP

Shengzhi Zhao

Abstract

High efficiency,low threshold laser crystal Nd3+ doped Sr5(PO4)3F,or NdSFAP has been reported in this paperUsing a tunable dyelaser(5750nm) and diode laser (LD) as pump source, we have realized the performance of total polarized NdSFAP laser at 10594nm and intracavity doubling NdSFAP/KTP laser at 5327nm.The lowest threshold and the highest slope efficiency are 25mJ and 49% for the NdSFAP laser pumped by dyelaser;the threshold and the slope efficiency are 9mW and 373% for the NdSFAP laser pumped by LD;the threshold and the lightlight efficiency are 121mW and 95% for the intracavity doubling NdSFAP/KTP laser pumped by LD, respectively
