Abstract
Multi-wavelength photochromic storage is a new optical storage method based on the photochromic principle. Experiments are carried out on 3 materials to test their sensitivity, crosstalk and operating time. One material of them is sensitive to lasers of 780 nm; the other, 650 nm and the last, 532 nm. The experimental results show: the three photochromic materials are all sensitive enough to record data. The crosstalk of 650 nm and 532 nm materials is neglectable, and they can be used in multi-wavelength optical storage as new photochromic materials. But the 780 nm material is also sensitive to 650 nm laser, and it results in obvious crosstalk. Therefore, the 780 nm material can't be of use only if it's improved greatly.
