ABSTRACT
Among the variety of ponderomotively induced density structures in laser produced plasmas in one dimension, it is shown by particle-in-cell simulations that the stable plateau formation at critical, subcritical, and above critical density is possible. Stimulated Brillouin backscattering is suppressed with increasing laser intensity.

    This paper deals with a statistical approach for description of the laser field interaction with underdense plasmas and modification of the laser beam temporal coherence during its propagation through a plasma at power well below the filamentation threshold. The main properties of the plasma...

    A laser-produced plasma has been studied in which there is a peak plasma density between critical and quarter-critical for a substantial amount of time (∼400 psec). The behavior of temporally and spectrally resolved light near the wavelength of the interaction laser λ0, is compared to...

    Evidence is presented that ion-acoustic waves associated with backscattered laser light are responsible for the observation of the blue-shifted feature in the backscatter direction. Backscattered light near the incident laser frequency, ω[sub 0], and near three-halves of the incident laser...

    The plasma wave produced in a stimulated Raman back scattering process in plasma is seen to be effective in the resonant Raman upshifted third harmonic generation of the same laser or of another laser of a slightly lower frequency. The process requires plasma density slightly lower than the...

    A plasma with a background flow along the direction of propagation of a laser beam is examined. The laser beam is subject to the beam-smoothing properties of a random phase plate. A simple model for the speckled properties of the laser beam is employed to show that the combined effect of the...

    Stimulated Raman scattering, stimulated Raman cascade, and the transition from Raman cascade into photon condensation, induced by linearly polarized intense laser interacting with an underdense uniform collisionless plasma, are studied by particle simulations. In addition to the stimulated Raman...

    Experiments in plasmas produced with 2 mm diameter gas filled targets preheated with 10 kJ of laser energy have shown that the stimulated Raman scattering (SRS) of a high intensity, 351 nm, beam is affected by the presence of a second, counterpropagating, high intensity beam and that has its...
