The properties of photoinduced birefringence and optical storage in azobenzene side-chain liquid crystal polymer films are investigated by means of CW laser at 532 nm and the Q-switched (8 ns) second-harmonic generation Nd:YAG pulse. According to the experimental results and numerical simulation, long-time optical storage based on photoinduced birefringence related to temperature field, molecular accumulation, molecular chain orientation are explained.
