Statistics of the single mode light in the transparent medium with cubic nonlinearity

В. Н. Горбачев, A. I. Zhiliba

The quantum statistics of the light in the transparent medium with cubic nonlinearity is considered. Two types of transparent media are treated, namely, the cold transparent medium with a ground working level and the inversion-free medium with the lasing levels of the same population. The spectra of light fluctuation are found on the basis of both Scully-Lamb and Haken theories. The conditions for the use of effective Hamiltonian are determined. Basing on the exact solution of the Fokker-Plank equation for the Glauber-Sudarshan P-function the inversion-free medium with cubic nonlinearity is shown to be the source of spontaneous radiation with non-Gaussian statistics.The quantum statistics of the light in the transparent medium with cubic nonlinearity is considered.

Measurements of light-intensity noise during nondegenerate two-wave mixing in a Kerr medium

R. Pizzoferrato, E. Pichini, Marco Marinelli +3 more

Measurements of light-intensity fluctuations have been carried out during cw nondegenerate two-wave mixing at visible wavelengths in an artificial Kerr medium. Taking advantage of the distinctive properties of artificial Kerr media, such as the high nonlinear efficiency and slow response, the zero-average component of optical noise has been revealed and completely characterized with regard to statistical and spectral features. Experimental results are discussed in the frame of a stochastic noise model including thermal fluctuations in the linear dielectric constant of the medium.Measurements of light-intensity fluctuations have been carried out during cw nondegenerate two-wave mixing at visible wavelengths in an artificial Kerr medium.

Photon statistics: classical and quantum fluctuations of scattered light in an optical anisotropic (ordered) liquid

Sergei M Arakelyan

The brief review of experimental results on the light scattering (both linear and nonlinear) in liquid crystals in critical range, which have been obtained by the original homodyne technique, is presented. The multiplicative nature of the molecular fluctuations in the medium under external field and physical consequences of that are discussed.
