Nondegenerate electron beam parametric amplifier 非简并电子束参量放大器
Based on the theory proposed by Walls et al, an experimental scheme of quantum non demolition ( QND) measurement for intensity difference fluctuations is put forward, which is realized though a nondegenerate optical parametric amplifier. 提出了一种强度差起伏量子非破坏性(QND)测量的实验方案,该方案通过一个非简并光学参量放大腔实现。
