Abstract

In this paper, a 2.2% doped Cr:LiSAF crystal with 1 mm in thickness is pumped by a 679 nm laser diode, and intracavity-doubled with NCPM KN crystal. Maximal output of TEMoo 3.15 mW of blue laser at 431.7 nm is obtained with the absorption power of 256 mW. The laser scheme shows a threshold of 96 mW and slope efficiency of 1.97%. Continuous-wave tunable output is demonstrated in the blue region of 423.4 - 445.5 nm through only changing temperature of KN crystal.
