Abstract
We report the efficient compact deep-blue laser at generation by intracavity frequency doubling of a continuous wave (cw) laser operation of a diode-pumped laser on the transition at . An LBO crystal, cut for critical type I phase matching at room temperature is used for second-harmonic generation (SHG) of the laser. At an incident pump power of , as high as of cw output power at is achieved with -long LBO. The optical-to-optical conversion efficiency is up to 34.7%, and the power stability in is better than .
