摘要: Warm phasematching LiNbO3 (Tpm ∼120 °C) has been used to achieve greater than 40% SHG efficiency of an acousto‐optic Q‐switched Nd:YAG laser. The growth high‐quality crystals suitable for efficient noncritical second‐harmonic generation is possible owing the significantly lowered index damage annealing temperature.
