Abstract

SBS parameters in xenon in the density range of 0.3 g/cm³ < ρ < 1.82 g/cm³ and at temperature 292.5 ± 0.1K were examined experimentally. It was shown that in the density range from 0.3 g/cm³ up to 0.6 g/cm³ SBS gain increases achieving the value of g ≈ 140 cm/GW. In the density range from 1 g/cm³ up to 1.5 g/cm³ SBS gain decreases down to the value g ≈ 43 cm/GW due to anomalous decrease of phonons lifetime (τph ≈ 10 ns at the density 1.5 g/cm³). When the density increases above the value 1.5 g/cm³ SBS gain increases again achieving the maximal value g ≈ 160 cm/GW at ρ = 1.82 g/cm³.
