摘要
Nonvolatile holographic recording is performed with green light in LiNbO3：Ce：Cu crystals. The refractiveindex change and the recording sensitivity are times better than those obtained by recording with red light, and higher optical fixing efficiency is obtained. Correspondingly, theoretical investigations are given.
