在一台小型TEACO2激光器上采用光栅调谐的方法获得了从9．23～10．64μm范围的多谱线输出，其中7条最强的谱线用非线性光学晶体AgGaSe2实现了二次谐波转换。在基波聚焦情况下，用一片优质的14mm长的晶体，获得了R（14）跃迁10．288μm的26％倍颇能量转换效率。
Multi-spectral output from 9.23 ~ 10.64μm was obtained by using a grating tuning method on a small TEACO2 laser. Among the seven most intense lines, the nonlinear optical crystal AgGaSe2 was used to realize the second harmonic conversion . In the case of fundamental focusing, a good 14 mm long crystal was used, yielding 26% of the energy conversion efficiency of an R (14) transition of 10.288 μm.
