| Abstract: | The two-photon storage properties of azo dye doped MO-PVA and EO-PVA polymer film have been reported. The excellent real-time and short-time storage of image information are obtained when the Ar+ laser is used as preexcitation light and He-Ne laser is used as storage light source. It is indicated that the storage mechanism is related to four energy level system of two-photon. The optimal preexcited power of Ar+ laser is about 0.28 W/cm2, and the minimum He-Ne storage power is less than 0. 2 W/cm2. |
