Dependence of the high-density holographic recording parameters of photopolymer on sample thickness
A novel holographic photopolymer was fabricated; the dependence of high-density holographic recording parameters such as exposure energy, exposure time, dynamic range, refractive index modulation and sensitivity on the sample thickness was studied experimentally. It shows that with the increase of sample thickness, the sensitivity decreases, the exposure energy, exposure time and dynamic range increase, but the change of index modulation is irregular.
