通过非相干白色光的预曝光，Sn 2 P2 S6铁电光折变晶体对Nd 3+：YAG激光（λ = 1.06 μm）的连续波辐射变得更加敏感。空间电荷的形成和全息图记录主要由扩散电荷输运控制，导致透射光栅的最终增益因子在约50 W/cm 2的激光强度下超过6 cm-1。
Ferroelectric photorefractive Sn2P2S6 crystals become more sensitive to cw radiation of a Nd3+: YAG laser (λ = 1.06 µm) by preexposure with incoherent white light. Space-charge formation and hologram recording are dominated by a diffusionlike charge transport, leading to an ultimate gain factor for transmission gratings that exceeds 6 cm−1 at a laser intensity of approximately 50 W/cm2.
