利用工作在2 μm附近的可调谐激光器,我们在GaAs-Al_(0.3)Ga_(0.7)As多层膜中观察到了二次谐波的产生。观察到反向传播谐波的相位匹配,并且对应于k2=2(k1−κ)<0,其中k1<κ/2,κ是周期性结构的波矢量。
Using a tunable laser operating near 2 μm we have observed second harmonic generation in a GaAs‐Al0.3Ga0.7As multilayer. Phase matching of the backward‐traveling harmonic wave is observed and corresponds to k2=2(k1−κ) <0 where k1<κ/2 and κ is the wave vector of the periodic structure.
