Statistics of energy fluctuations and spatial distribution of Stokes-pulse intensities in steady-state stimulated Raman scattering
Abstract
Probability distribution of Stokes-pulse energies and spatial intensity distribution of Stokes radiation in steady-state stimulated Raman scattering (SRS) are experimentally studied. In the Stokes pulses generated from quantum noise (conversion efficiency approximately = 10(exp -6)) 70% energy fluctuations are observed with asymmetric probability distribution. Fluctuations decrease and the intensity distribution becomes more symmetric if the SRS is initiated by external Stokes radiation. In both SRS regimes the spatial distribution of the Stokes intensity shows significant pulse-to-pulse variations.
