摘 要: | 中用两个工作在近简并四波混频状态下的相位共轭反射镜PCM组成了一个相位共轭腔PCR(本文记这种PCR为NPCR),并在其中实现了稳定振荡.本文通过引入PCM的显含频率的光束变换矩阵,首次推出了NPCR中的高斯模及其稳定性条件,得到的某些结论在一定近似程度上被中的某些实验结果所证实.一、显含频率的PCM变换矩阵在推导PCR中的高斯模时,首要的问题是需要定义一个合适的光束变换矩阵来描述PCM的运转.我们以q、ρ、W、λ、ω分别代表高斯光束的复曲

Gaussian mode of a resonator formed by two phase-conjugate mirrors |
| |
Abstract: | By introducing the transfer matrix of phase-conjugate mirror (PCM) which has explicite frequency variable, it has been derived that the Gaussian modes and stability condition in a phase-conjugate resonator (PCR) bounded by two PCM’s which are formed via a nondegenerat four-wave mixing. The effect or frequency-flipping of PGM on the mode properties of the PCR has been discussed. |
