Abstract
Stimulated Brillouin scattering of KrF laser radiation focused in SF6 gas at pressures of 1.4 to 9.8 atm has been studied experimentally. For an input linewidth of 0.08 cm−1 and focal lengths of 1 and 2 m, reflectivities of 80% have been measured. Pulse compression up to peak intensities of two times the pump intensity has been achieved in a pulse that is partially phase conjugate to the pump pulse. At high pressures a short backward Raman spike was observed preceding the Brillouin backscattered signal.
