The phase-matching curve of GCOB crystal was calculated and experimentally measured. The measured data of phase-matching angle are well fit to the calculated curve. The second-harmonic generation conversion efficiency of a Q-switched Nd:YAG laser with a GCOB crystal of 5 mm in length is about 26.7%. Comparing the conversion efficiency with that of the same length BBO crystal, the effective nonlinear coefficient is estimated to be close to that of BBO crystal.
