摘要
测量了偶氮材料 MO/PVA和 EO/PVA的光致双折射 ,其值约为δn=2 .7× 1 0 - 3.在同偏振态两路简并四波混频光同时作用于样品同一区域的条件下 ,研究了该材料的双波长共存特性 ,记录了光点存储和图象存储 ,并分析了双波长共存的竞争机制 .
A large photoinduced birefringence of MO/PA was measured:δn=2.7×10 -3 .With two sets of DFWM of 488nm laser and 532nm laser,dual wavelength storage has also been performed.It is analyzed the competition and coexistion mechanism of this storage.Both photoelectric and image storage records were reported.
