英文摘要：

A fluoric photopolymer for holographic recording materials is synthesized. The exposure curve is measured, and the exposure energy constant 12.0 mJ/cm^2 is obtained by curve fitting method. The changes of the reflective efficiency of the present synthesized photopolymers with the recording space frequency are detected, and the refractive index modulation variations with the recording space frequency are calculated according to coupled wave theory. The results reveal that the reflection efficiency and the refractive index modulation of the photopolymers decrease with increasing the recording space frequency, and the maximum refractive index modulation is up to 3.33 × 10^-3.
