Abstract

We report cw blue light generation by using a periodically poled $\mathrm{MgO}:{\mathrm{LiNbO}}_3$ crystal with a ridge waveguide pumped by a fiber Bragg grating stabilized laser diode with $0.25\mathrm{nm}$ spectrum width in the coherent collapse regime. Blue light generation of $73\mathrm{mW}$ with 27% conversion efficiency and a wide temperature tolerance of $5.7°\mathrm{C}$ were attained.
