Abstract

We generated efficient blue laser output at 454 nm by intracavity frequency doubling of a continuous-wave (cw) diode-pumped Nd : Y Li F 4 (Nd:YLF) laser at 908 nm based on the F 3 / 2 4 I 9 / 2 4 transition. With 32.8 W of incident pump power at 880 nm and the frequency-doubling crystal Li B 3 O 5 , a level as high as 4.33 W of cw output power at 454 nm is achieved, corresponding to an optical conversion efficiency of 13.2% with respect to the incident pump power. To the best of our knowledge, this is the first blue laser at 454 nm generated by intracavity frequency doubling of a diode-pumped Nd:YLF.
