Optical pulse compression in a cholesteric liquid crystal
Abstract
A 20-ns laser pulse is compressed to nearly 2.5 ns in a 10-cm-long sample of liquid-crystal cholesteryl oleate in the isotropic phase. Pulse compression in a length as short as only 5 cm has been observed. A semiquantitative explanation is given in terms of stimulated Brillouin scattering.
