摘要
用炉温下降法生长出尺寸为φ20×60 mm的AgGaSe2单晶体。在12 mm长，切角为55°的AgGaSe中，获得了TEA CO2激光的倍频输出，其功率转换效率为1.12％。泵浦阈值和破坏阈值分别为3 MW/cm2和11 MW/cm2。还讨论了泵浦束的发散角对二次谐波转换效率的影响。
Abstract
AgGaSe2 crystal of φ20×60 mm has been grown by the method of oven temperature drop. The frequency-doubled (5.3 μm) output and the power conversion efficiency of 1.12% have been obtained for second harmonic generation of TEA CO2 laser (10.6 μm). The pumped and the damaged threshold are about 3 MW/cm2 and 11 MW/cm2, respectively. We have also discussed the effect of the beam divergence on the second harmonic conversion efficiency.
