光折变晶体中二波耦合光强依赖现象和各向异性热透镜效应
INTENSITY-DEPENDENT TWO-WAVE COUPLING ANDANISOTROPIC THERMAL-LENS EFFECT IN PHOTOREFRACTIVE CRYSTAL
【摘要】 实验发现,掺Ce离子的光折变晶体KNSBN中二波耦合光强依赖现象和各向异性热透镜效应有共生关系.光吸收引起晶体温升乃至引起.光折射率的增加是产生这种现象的主要原因.
【Abstract】 The phenomenon of intensity-dependent two-wave coupling in company with anisotropic thermal-lens effect is found in Ce doped KNSBN photorefractive crystal. The increase of extraordinary index of refraction with temperature of the crystal plays an important role.
