  4. The efficient sppc had been performed with 1 - hz - repetition - rate 532nm nanosecond pulses, in which phase conjugate reflectivity as high as 21. 5 % was obtained. when sppc were operated in ce : batio3 with 532nm, 632. 8nm and 790nm cw lasers, the maximum sppc reflectivity of 54. 1 %, 88. 2 % and 80. 5 % were obtained, respectively. unlike the results reported before that four - wave mixing by stimulated photorefractive backscattering ( spb - fwm ) only exists at short wavelengths while four - wave mixing by total internal reflection ( tir - fwm ) only exists at long wavelengths, both of these two mechanisms coexist at all wavelengths from 532nm to 790nm in our experiments
