我们报道了掺钌和铁的LiNbO 3晶体的非挥发性全息记录。当选通光束（蓝光）同时入射到晶体上时，可以在632.8nm的波长下记录非易失性全息图。记录的全息图可以成功地固定和转换成一个非易失性全息图保持全息图的强度几乎不变。记录灵敏度和动态范围随Fe浓度的增加而增大。在0.5mm厚的样品上获得了0.12cm/J的灵敏度和0.53的动态范围。
We report the nonvolatile holographic recording in the Ru and Fe doped LiNbO3 crystal. The nonvolatile hologram can be recorded at a wavelength of 632.8 nm when the gating beam (blue light) is simultaneously incident on the crystal. The recorded hologram can be successfully fixed and transformed into a nonvolatile hologram keeping the hologram strength almost unchanged. The recording sensitivity and dynamic range increase with the increase of the Fe concentration. The sensitivity of 0.12 cm/J and the dynamic range of 0.53 are obtained at the 0.5-mm-thick sample.
