A comparative study of laser second harmonic generation in some crystals
G C Bhar A M Rudra P K Datta U N Roy V K Wadhawan T Sasaki
Comparison of the conversion efficiency for efficient second-harmonic generation of Nd: YAG laser radiation is reported for KDP, LAP, KTP, BBO and LBO crystals. Conversion efficiencies as high as 50% and 46% were obtained for our laboratory-grown KDP and LAP crystals respectively, for power densities well below their damage thresholds.
