We report the first known observation of amplified reflection through degenerate four-wave mixing at 10.6 microm. Reflectivities of over 100% are reported in both n-type and p-type germanium at pump intensities of about 100 MW/cm(2). The maximum reflectivity reported is 800% in p-type Ge.
我们报道了在10.6微米处通过简并四波混频实现放大反射的首次已知观测结果。在泵浦强度约为100兆瓦/平方厘米时，n型和p型锗中的反射率均报告超过100%。所报道的p型锗中的最大反射率为800%。
