Qc. Guan et al., SELF-PUMPED PHASE-CONJUGATION IN KTA0.48NB0.52O3 CRYSTALS DOPED WITH DIFFERENT FE CONCENTRATIONS, Optics communications, 116(4-6), 1995, pp. 416-420
Experimental results concerning phase conjugation obtained from two se
lf-pumped KTN crystals doped with 0.2 and 0.4wt% Fe, respectively, are
compared. The origins of the phase conjugate reflection in these two
crystals due to different mechanisms are discussed.
