| Abstract: | A continuous-wave(CW) 457 nm blue laser at power as high as 4.2 W is demonstrated by using fiber coupled laser diode module to pump Nd:YVO4 and using LBO as intra-cavity SHG crystal.With optimization of laser cavity and crystals parameters,the laser operates with a very high efficiency.When the pumping power is about 31 W,the output power reaches to 4.2 W,and the optical to optical conversion efficiency is about 13.5% accordingly,and the stability of the output power is better than 1.2% for 8 h. |
