受驱动的关联发射激光:双模亚泊松光

Driven Correlated Emission Laser: Two Mode Sub Poissonian Light

如果在关联发射的基础之上再引入原子相干，这样的系统可产生明亮的双模亚泊松光。运用Ｓｃｕｌｙ－Ｌａｍｂ理论计算ＭａｎｄｅｌＱ因子，一方面，当相对相位和相对振幅的量子噪声被抑制到真空噪声水平时，平均模呈现亚泊松光子分布；或者当平均相位和平均振幅的量子噪声被抑制到真空噪声水平时，相对模呈现亚泊松光子分布，ＭａｎｄｅｌＱ因子的最佳值均可达到－０．５。在上述两种情况下，每个关联发射激光（ＣＥＬ）模呈现亚泊松光子分布，ＭａｎｄｅｌＱ因子的最佳值均可达到－０．２５。

If new atomic coherence is introduced into correlated emission laser systems, such systems can produce bright two mode sub Poissonian light. Using Scully Lamb theory the Mandel Q parameter is calculated. When quantum noises of relative amplitude and relative phase drop to vaccum noise levels, average mode exhibits sub Poissonian photon distribution; when quantum noises of average amplitude and average phase drop to vaccum noise levels, relative mode exhibits sub Poissonian photon distribution; the optimum Mandel Q parameter is -0.5. In the above two cases, each of two CEL modes exhibits sub Poissonian photon distribution with optimum Mandel Q parameter of -0.25.
