X. Gao et al., INCIDENT BEAM CONDITION DEPENDENCE OF RATIO BETWEEN 2 PHASE-CONJUGATETRANSMISSIVITIES IN DOUBLE-PHASE-CONJUGATE MIRROR, Optics communications, 106(4-6), 1994, pp. 258-262
It is observed that the ratio between two phase-conjugate transmissivi
ties of two incident light ways depends on incident beam position rath
er than the ratio of two incident beam intensities in a KNSBN:Cu doubl
e-phase-conjugate mirror. A model with two one-dimensional interaction
processes in an interaction region is presented and explains the expe
rimental results. On the nature of the double-phase-conjugate mirror,
the two phase-conjugate transmissivities are not always equal.
