A Microchip Tunable Blue Laser Source Based upon Cr:LiSAF in Contact with KN Crystal |
| |
| Abstract: | In this paper, a microchip laser consisted of 2.2% doped Cr:LiSAF crystal and NCPM KN(KNbO3) crystal and pumped by a 679 nm laser diode is reported. The maximal output of TEM00 4.76 mW of blue laser at 431.7 nm is obtained with the absorption power of 304.6 mW. The laser shows a threshold of 76.2 mW and slope efficiency of 2.08%. Continuous-wave tunable output is demonstrated in the blue region of 423.4～445.5 nm through only changing temperature of KN crystal controlled by PID controller. |
