Abstract
The technique of Brillouin induced four wave mixing (BIFWM) is currently receiving considerable attention because it can be used with pulsed lasers to achieve phase conjugation with extremely high reflectivities. Reflection coefficients in the region of 106 have been reported by some authors, and over 70% of the pump beam can be reflected into the conjugate beam, providing a very efficient usage of the pump beam energy [1]. Using a variation of the technique it is alternatively possible to produce the phase conjugate of very weak signals corresponding to about 10-14J, or about 105 photons [2].
