Phase-conjugate interferometry by using dye-doped polymer films
Abstract
The properties of phase conjugate (PC) beams generated by an erythrosin/polyvinyl alcohol film are briefly reviewed along with demonstrations of PC interferometries, and an experimental study of the time dependence of the phase difference between saturable absorption and holographic components of the PC signal is reported. The results show that the phase difference between two components of PC signals changed temporally with a period of about nine minutes and reached 110 deg five minutes after the initiation of degenerate four-wave mixing at the pump beam intensity of 1 W/sq cm.
