Continuous-wave laser at 440 nm based on frequency-doubled diode pumped Nd:GdVO4 crystal
Résumé
We present for the first time, to the best of our knowledge, a frequency-doubled Nd:GdVO4 laser operating in a cw on the pure three-level laser line at 880 nm. We obtained 300 mW at 440 nm for 23 W of incident pump power at 808 nm. Moreover, with a 25% output coupler we obtained a cw power of 1.9 W at the fundamental wavelength at 880 nm.
