Abstract
Since the observation of self-frequncy scaning with a passive phase-conjugate mirror coupled to a dye-laser cavity in 1984, much attention has been paid to frequency detuning in photorefractive (PR) wave mixing. Such a phenomenon has been widely studied in various photorefractive oscillators.(1) In this paper, we present the experimental results of frequency shift (f-shift) in our mutually pumed phase conjugator (Bridge conjugator)(2) and demonstrated to be dramatically dependent upon the power density of pumping beams.
