Abstract

We demonstrate for the first time to our knowledge intra-cavity frequency doubling (ICFD) of an edge-emitter diode laser using a 10 mmlong 5.0 μm periodically poled LiNbO₃ (PPLN) crystal. An optical output power of 33 mW second harmonic blue light at 490.5 nm is generated at 1.0 A injection current, equivalent to an overall wall-plug efficiency of 1.8%. The measured M² values of blue beam are 1.7 and 2.4 along the fast and slow axis.
