摘要
在一台小型连续波(CW)CO2激光器上用光栅调谐获得了从9.23～10.65 μm范围内20条谱线输出,用一片8 mm×8 mm×15 mm红外非线性光学晶体AgGaSe2实现了上述谱线的二倍频输出.实验测得10P(20)谱线的倍频光输出为2.1 μW,相位匹配接收外角△θ外·L=2.1°·cm.
Abstract
A miniature continuous-wave CO2 laser is tuned to operated in -20 single spectrum lines from 9.23 to 10.65 μm, all these lines are converted respectively by a IR-nonlinear optical crystal of AgGaSe2 with size 8 mm×8 mm× 15 mm into the second harmonics. Second-harmonic output at 5.3μm of the order of 2.1 μW has been experimently obtained for the 10P(20) line, the external angular acceptance angle △θext · L is 2.1°·cm.
