Title: Thresholds of absolute instabilities driven by a broadband laser

Abstract

Absolute instability thresholds for stimulated Raman scattering and two-plasmon decay driven by a broadband laser pulse are evaluated numerically. The scalings of the calculated thresholds with density scale length, temperature, and central wavelength are qualitatively similar to existing analytic results. The threshold values, yet, reflect significant quantitative differences. Comparisons between thresholds calculated for various broadband power spectra suggest a universal scaling of the threshold intensity with laser coherence time ($$\tau_{c}$$). For SRS Ithr ∝ $$\tau_{c}^{-1/3}$$, and for TPD Ithr ∝ $$\tau_{c}^{-1/2}$$ .
