利用532 nm的纳秒脉冲记录光折变复合材料光栅。在4 mJ/cm（2）照明下，最大衍射效率达到56%，建立时间仅为300 μ s（t（1）），与连续光束写入相比，记录速度快了一个数量级。这种快速响应使得需要100 Hz或更高帧率的光学处理应用成为可能。由于写入脉冲的持续时间短，记录对振动不敏感。(c)2006年，美国物理学会。
Individual nanosecond pulses at 532 nm are applied to record gratings in photorefractive composite. At 4 mJ/cm(2) illumination, maximum diffraction efficiencies of 56% have been reached with a build-up time of only 300 mu s (t(1)) demonstrating one order of magnitude faster recording compared to writing with continuous wave beams. This fast response enables applications in optical processing requiring frame rates of 100 Hz or more. Due to the short duration of the writing pulses, the recording is insensitive to vibrations.
