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 1.2 W SHG of blue lights at 465 nm is generated at 45 A injection current, equivalent to an overall wall-plug efficiency of 1.33%.
