研究了 0°切和 45°切 Ce:Ba Ti O3晶体的受激光折变散射自泵浦相位共轭 (SPS- SPPC)特性 ,获得的最大共轭光反射率分别为 6 7%和 80 %。比较了两种样品内部光路形成的特点 ,实验结果表明 ,45°切样品不仅具有更高的反射率 ,而且入射角在较大范围内都能获得较高的共轭光反射率。对此作了理论分析。
The phase-conjugate (SPS-SPPC) characteristics of laser-induced refraction and scattering of Ce: Ba Ti O3 crystals at 0 ° and 45 ° were studied. The maximum conjugate light reflectance was 67% and 80% . The experimental results show that the 45 ° cut samples not only have higher reflectivity, but also have higher incident light reflectance in a wide range. This makes a theoretical analysis.
