Abstract
A compact blue laser was generated by intracavity frequency doubling based on quasi-phase-matched second-harmonic generation (SHG) in a MgO-doped periodically poled lithium niobate bulk crystal. A 49 single-transverse-mode edge-emitters laser bar with antireflective coating was used as a pump source. An optical output power of 1:2W SHG of blue lights at 465nm is generated at 45A injection current, equivalent to an overall wall-plug efficiency of 1.33%.
