High Efficient Single Pass Second Harmonic Generation of a Broad Area Laser Diode in an External Cavity using a PPLN Waveguide Crystal

High Efficient Single Pass Second Harmonic Generation of a Broad Area Laser Diode in an External Cavity using a PPLN Waveguide Crystal

The infrared light of a broad area laser diode in an external cavity is frequency doubled by the use of a PPLN waveguide crystal. More than 45 mW visible light are generated resulting in 33% internal conversion efficiency.
