摘要：
In this work we represent a highly efficient (> 20%) CW second harmonic generation in PPKTP and PPLN crystals. As a fundamental source we used a high power (> 24W) single-frequency (< 50k-Hz linewidth) linearly polarized CW Er:Yb fiber laser. This laser was used in a single pass schematic to achieve more than 5W average power SHG in 780nm. Single pass conversion efficiency of > 20% for PPLN and > 7% for PPKTP was demonstrated. We also demonstrate a possibility of single mode fiber delivery for this SHG Source with excellent beam quality (M-2 < 1.1). Pump power dependency of conversion efficiency and other SHG characteristics for PPLN and PPKTP Would be presented and compared.
