69% Efficient continuous-wave second-harmonic generation in lithium-rich lithium niobate.
Lithium-rich lithium niobate fabricated by vapor transport equilibration is used to frequency double the output of an injection-locked Nd:YAG laser. Internal doubling efficiencies as high as 69% and powers of as much as 1.6 W are achieved by resonant external cavity second-harmonic generation. No evidence of photorefractive damage is observed at the operating temperature of 234 degrees C.
