Intracavity frequency doubling of a Nd:YAG laser with an organic nonlinear optical crystal
Abstract
Intercavity second harmonic generation of green 532 nm light in a quasi-cw 1064 nm Nd:YAG laser was demonstrated using organic nonlinear optical crystals of DAN (4-(N,N-dimethylamino) 3-acetamidonitrobenzene) immersed in index matching fluid contained in an antireflection coated cuvette. This technique permits crystals to be used directly from solution growth without polishing or antireflection coating them. Up to 0.56 mW peak power of 532 nm light was generated from 2.3 W of intracavity 1064 nm peak power in 100 microsecond pulses. Preliminary results are reported on true cw intracavity harmonic generation with antireflection coated DAN crystals.
