Efficient second-harmonic generation of Nd:YAG laser radiation using warm phasematching LiNbO3

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 of high-quality LiNbO3 crystals suitable for efficient noncritical second-harmonic generation is possible owing to the significantly lowered index...

Zusammenfassung: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 of high-quality LiNbO3 crystals suitable for efficient noncritical second-harmonic generation is possible owing to the significantly lowered index damage annealing temperature.
