摘要: 在前文的基础上求得了简并参量放大系统在位相不匹配情况下的Fokker_Planck方程一个新 的解析解，然后通过准位相匹配(QPM)，计算振幅的量子起伏. 这一结果在不考虑损耗(k =0)情况下，与已知的按解Langevin方程求得的结果为一致. 对于一般的考虑损耗(k ≠0)情况，我们也得出损耗系数k对压缩态特性的影响.
Abstract: A new analytical solution for the phase_mismatched Fokker_Planck equation of deg enerate parametric amplification, and its application in evaluation of the ampli tude quantum fluctuation after passing through the quasi_phase_matching(QPM) dev ice is presented. The calculated results for QPM device, agree with that of the Langevin equation in the case of no loss k=0, and give a general solution fo r k≠0, from which we can derive the influence of squeezing on the loss coef ficient k.
