摘    要:
研究了偶氮基染料掺杂薄膜MO-PVA和EO-PVA的双光子存储特性。在对薄膜用Ar^+激光作预激发下实现了He-Ne激光的红光存储。获得了实时和短时存储照片。光电记录存储曲线,分析了双光四能级系统的存储机制。实现确定了最佳预激发功率约为0.28W/cm^2,最小He-Ne光可存储功率密度低于0.2W/cm^2。

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.
Keywords:biphoton   AZO dye films   organic material PVA (polyingl alcohol)  storage character
