Multiple-short-pulse stimulated Brillouin scattering for trains of 200 ps pulses at 1.06 mu m

High-reflectivity, good-fidelity multiple-short-pulse stimulated Brillouin scattering phase conjugation is demonstrated for pulse trains containing pulses of 200-ps duration with interpulse separations of 7.5 ns. The reflectivity is seen to build up from pulse to pulse to a final value of 52%. The B...

Description
Summary:High-reflectivity, good-fidelity multiple-short-pulse stimulated Brillouin scattering phase conjugation is demonstrated for pulse trains containing pulses of 200-ps duration with interpulse separations of 7.5 ns. The reflectivity is seen to build up from pulse to pulse to a final value of 52%. The Brillouin medium is high-pressure SF/sub 6/ gas having a Brillouin lifetime of 35 ns. Severe competition with optical breakdown is discussed.< >
