测量了RCOB（R = Gd，Y）晶体的非线性光学系数。deff（有效非线性光学系数）的空间分布，随后确定。我们的实验表明，最大deff发生在第二象限。6mm长（113.2°，47.4 °）切割的GdCOB和5mm长（113°，36.5 °）切割的YCOB的二次谐波产生效率分别达到48%和41.5%。首次报道了GdCOB的腔内倍频。
The nonlinear-optical coefficients of RCOB (R = Gd, Y) crystals are measured. The spatial distribution of deff (effective nonlinear-optical coefficient) is subsequently determined. Our experiments show that the maximum deff occurs at the second quadrant. The second-harmonic generation efficiency reaches 48% for a 6 mm long, (113.2°, 47.4°)-cut GdCOB, and 41.5% for a 5mm long, (113°, 36.5°)-cut YCOB, respectively. The intracavity frequency doubling of GdCOB is reported for the first time.
