Blue generation at 456 nm by single-pass frequency-doubling of a Nd:GdVO/sub 4/ micro-laser in a periodically poled MgO:LiNbO/sub 3/ ridge-type waveguide

摘要

This paper reports on our work toward scaling deep blue light by single-pass SHG-QPM of a 912-nm Nd:GdVO/sub 4/ laser in a PPMgLN ridge-type waveguide. The maximum measured blue power was 93 mW with an infrared-to-blue conversion efficiency of 14.6%.
