LLE Review, Volume 67 119 The experimental study of parametric instabilities in longscale-length laser plasmas is very important for inertial confinement fusion (ICF). Backscattered light near the incident light wavelength has been observed in many laserplasma experiments and is generally attributed to stimulated Brillouin scattering (SBS).1,2 Stimulated Brillouin scattering is a parametric ins...

We analyze the effect of phase-matched third-harmonic generation on the existence and stability of (1 1 1)-dimensional bright and dark spatial solitary waves in optical media with a cubic (or Kerr) nonlinear response. We demonstrate that parametric coupling of the fundamental beam with the third harmonic leads to the existence of two-color solitary waves resembling those in a x (2) medium and t...

We show that plane-wave singly resonant optical parametric oscillators exhibit a temporal modulation instability when pumped a certain number of times above threshold. Previously, this instability threshold was predicted, with a model neglecting variations in pump power, to occur at around 4.61 times oscillation threshold. We consider here the full self-consistent interaction between pump, sign...

Increasing laser power is essential to improve the sensitivity of interferometric gravitational wave detectors. However, optomechanical parametric instabilities can set a limit that power. It major importance understand and characterize many parameters effects influence these instabilities. Here, we model with high degree precision optical mechanical modes involved in instabilities, such our be...
