Photon statistics in saturated mphoton amplification and attenuation of coherent light
Abstract
The change of photon statistics of a nearly coherent singlemode light beam travelling through a saturable mphotonamplifying or absorbing medium ( m = 1, 2, …) is theoretically investigated. With the help of an approximation scheme valid for overlinen ≫ 1, Δ n^{2} ≪ overlinen^{2} ( overlinen mean value and Δ n^{2} variance of the photon number) an analytical expression is derived for the quantity Δ n^{2}/ overlinen. The results holds for arbitrary values of the initial population inversion and of the degree of saturation. It turns out that for both amplification and attenuation processes after sufficiently strong interaction Δ n^{2}/ overlinen tends to an asymptotic value.
