Effect of Intensity on Properties of Nonvolatile Holographic Recording in (Cu,Ce):LiNbO3 Crystal
The effect of intensity on the recording sensitivity and saturation diffraction efficiency was studied experimentally in holographic recording of (Cu,Ce):LiNbO 3 crystal by use of a red beam for recording and a blue for sensitizing. The sensitizing light increases the recording sensitivity, and the saturation behavior will appear with enough high intensity of sensitizing light. The recording light increases the recording slope defined as the initial time derivative of the square root of the diffraction efficiency by sublinear relation I x r (x<1) and thus the recording light decreases the recording sensitivity. Dependences of the saturation diffraction efficiency on the intensities of the recording and sensitizing light show that there is the maximum saturation diffraction efficiency.
