摘要
We describe , high-efficiency double-phase-conjugate mirror in a Ce-doped strontium barium niobate crystal by using a low-power He-Ne laser at a 633-nm wavelength. A phase-conjugate transmissivity of as high as 30% was observed. The dependence of the transmissivity on the incident angle was measured. It was also observed that the phase-conjugate signal varied with time pseudoperiodically with a period of ap 35 min. This variation is due to the competition between the double phase conjugation and beam-fanning effects.
