We have observed for the first time simultaneous occurrence of phase conjugation and pulse shortening in stimulated back scattering of nanosecond laser pulses from thin film of smectic and nematic liquid crystals, and from thick samples of isotropic cholesterics. Aberration correction capability and high compression ratio are obtained.
