Title: Frequency mismatch in stimulated scattering processes: An important factor for the transverse distribution of scattered light

Abstract

A 2D cylindrically symmetric model with inclusion of both diffraction and self-focus effects is developed to deal with the stimulated scattering processes of a single hotspot. The calculated results show that the transverse distribution of the scattered light is sensitive to the longitudinal profiles of the plasma parameters. The analysis of the evolution of the scattered light indicates that it is the frequency mismatch of coupling due to the inhomogeneity of plasmas that determines the transverse distribution of the scattered light.

  • Group-velocity mismatch between the pump and Stokes pulses and the inertia of optical nonlinearity are shown to modify scenarios of slow-light evolution of laser pulses accompanying stimulated Raman and Brillouin scattering (SRS and SBS) of light. In the transient regime of SRS and SBS, the inertia of nonlinear polarization of a medium shifts the peak of an amplified Stokes field envelope relative to the input Stokes pulse. This shift is sensitive to the shape of input laser pulses and is controlled by the SRS and/or SBS gain, the damping time of the optical phonon wave, and the delay time betweenmore » the input pump and Stokes pulses. In the regime where both the inertia of nonlinear polarization of an SRS medium and group-delay effects are significant, stationary modes of the Stokes field may exist in the frame of reference propagating with the group velocity of the pump field. The maximum group delay attainable for such modes of the Stokes field is limited, similar to the steady-state regime, by the ratio of the steady-state SRS gain to the Raman gain bandwidth.« less
  • Sum-frequency generation from the surface of an isotropic gyrotropic medium by two normally incident homogeneously elliptically polarised Gaussian beams is studied theoretically. Analytic expressions, completely describing the transverse spatial distribution of the intensity and polarisation in the cross section of the reflected beam at the sum frequency, were derived taking into account both the local and nonlocal contributions of the quadratic nonlinearity of the medium thicknesses and the nonlinear contribution of its surface. It is shown that a special selection of the parameters of the fundamental waves allows one to determine components of the surface susceptibility tensor.

  • The stimulated Brillouin scattering spectrum from a plasma is determined by the ion acoustic normal mode frequencies, which are dependent on the ion temperature and flow velocity. Thus these quantities are indirectly measured by the scattered light. The frequencies of ion acoustic normal modes and stimulated Brillouin scattered light are calculated for a model plasma formed by collisionlessly interpenetrating ion beams by assuming the ion--ion two-stream instability is marginally stable. The spectrum differs measurably from the spectrum expected from the hot, stationary plasma created by collisional stagnation. Comparison of the scattered light spectra for these two limiting cases suggests thatmore » careful observation of the scattered light near the laser frequency is a potentially useful diagnostic of the collisionality of interpenetrating ion beams.« less
  • Experiments examining nonlinear scattering mechanisms of high intensity (2{times}10{sup 18}W/cm{sup 2}) laser light in underdense plasmas were performed. Redshifted second harmonic emission at 45{degree} from the directly backscatterd direction was observed from field ionized plasmas having electron densities ranging up to 10{sup 19}cm{sup {minus}3}. This result is consistent with the doubling of stimulated Raman scattered light from large plasma electron density gradients produced by ponderomotive cavitation. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
