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