摘要
通过解非简并光学参量放大的Fokker Planck方程 ,得出压缩态光的腔内最大压缩的量子起伏为 1 16 (真空起伏为 1 4 ) ,与已知的简并光学参量放大情形腔内最大压缩为 1 8相比 ,压缩度提高了一倍 .
In this paper, we present the analytical solution of the Fokker-Planck equation of non-degenerate optical parametric amplification(NOPA)for generation of squeezed light. The maximum intra-cavity compression of squeezed light derived from the analytic cal solution is 1/16(vacuum fluctuations 1/4). To compare it with that of the previous result 1/8 of degenerate optical parametric amplification( DOPA), it seems that the squeezing for NOPA is superior to the squeezing for DOPA.
