Simultaneous occurrence of phase conjugation and pulse shortening in stimulated scattering in liquid crystal mesophases
Abstract
Stimulated Brillouin scattering with simultaneous phase conjugation and pulse shortening is observed in thin films of nematic and smectic liquid crystals, and from bulk samples of isotropic liquid crystals (cholesterics). Compression ratios as high as 20, and capability for the correction of severe distortions by the phase conjugation effect, are shown. In some cases, evidence of interference effects from a stimulated Raman component is found.
