| 摘 要： | 为使激光诱导动态光栅产生在空间上可分辨的高效率衍射光，光栅介质必须足够薄以满足光栅条件，但动态光栅自衍射效率却又随介质厚度的增加而增加，我们提出用相位匹配的周期性薄光栅组可解决这一矛盾，并在实验上用周期性热效应光栅对理论进行了验证。

| Abstract: | In order to produce high efficiency and resolvable diffraction light from dynamic grating,the medium for grating must be enough to satisify the thin grating condition,but the diffraction efficiency increased with the thickness of medium.We solved this problem with the periodic thin gratings in phase matching,and verified the results by periodic thermal gratings in experiment. |

| Keywords: | periodic dynamic grating self diffraction thermal effect |
