PHOTON STATISTICS IN STIMULATED RAMAN-SCATTERING OF SQUEEZED LIGHT

Photon statistics of stimulated Raman scattering of squeezed light are considered including additive noise . The phonon system is assumed to be in chaotic or squeezed chaotic states . The influence of nonlinear dynamics is established on the initial non-classical features of light adopting quasidistribution related to anti-normal ordering, photocount distribution, its factorial moments and principal squeezing parameter . It is shown that the initial non-classical effects are increased by the nonlinear dynamics provided that the Stokes mode is less amplified than the anti-Stokes mode is damped, whereas in the opposite case the non-classical effects are swiftly smoothed out . The frequency detuning can be optimized to have maximum non-classical effects, which can periodically return . However, above a certain bound the non-classical effects are missing with frequency detuning, and also with increasing phonon number, even if the phonon system is squeezed . Small initial squeezing can be increased by the nonlinear dynamics, whereas strong squeezing can only be diminished. © 1990 Taylor & Francis Ltd.
