Yj. Zheng et al., HIGH-EFFICIENCY BRIDGE DOUBLE PHASE-CONJUGATE MIRRORS IN CU-DOPED (K0.5NA0.5)(0.2)(SR0.61BA0.39)(0.9)NB2O6 CRYSTALS, JPN J A P 1, 34(9B), 1995, pp. 5405-5407
In this paper, we report the formation of high-efficiency double phase
-conjugate mirrors with the bridge incident geometry in Cu-Doped (Ka(0
.5)Na(0.5))(0.2)(Sr0.61Ba0.39)(0.9)Nb2O6 (Cu:KNSBN) crystals. These br
idge double phase-conjugate mirrors have high efficiency, even under l
ow incident power. For crystals with different absorption coefficients
, the optimum incident geometries of the bridge double phase-conjugate
mirrors were observed and discussed.
