Abstract


The dependence of phase conjugate efficiency and fidelity on interaction, coherence and acoustic lengths has been investigated in detail in SF6 and CF2Cl1. Two distinct regimes of time scales. broad and narrow bands. have been evolved from the combination of these length scales. It is found that the phase conjugate efficiency and fidelity improve dramatically in the narrow band regime.

Keywords


Phase conjugation; stimulated Brillouin scattering; interaction length; coherence length; acoustic length; fidelity.
