Stimulated thermal scattering of laser light at an exothermal reaction front in a dielectric gas waveguide

Two types of stimulated thermal scattering can occur at a laminar flame front - stimulated thermochemical scattering (STCS) may be observed when light travels in a waveguide near the reaction front; stimulated scattering by the front (SSF) is a consequence of the reflection and amplification of the signal by the front at near-Brewster incidence angles. The amplification factor for STCS and the reflection coefficient for SSF are calculated, and it is shown that STCS and SSF may dominate the more familiar stimulated thermal scattering (STS).
