三甲川菁染料绿光高密度光存储研究

High density optical storage property of cyanine dye by green laser

摘要: 利用旋涂法制备了三甲川菁染料掺杂高分子薄膜,室温下采用波长为532nm、数值孔径为0.65聚焦物镜的绿光存储装置研究了该染料薄膜的光存储特性。结果表明,三甲川菁染料薄膜在420nm～590nm区域内有两个吸收峰,可作为与532nm绿光半导体激光器相匹配的光存储材料。在激光功率为15mW、刻录速度1m/s的条件下,得到了记录线宽约600nm、反射率对比度为21%的结果。

Abstract: A cyanine dye polymer film is made by spin-coated method,and the property of the film is studied with green light recording system with NA of 0.65 at room temperature.In the range of 420nm～590nm the film shows two strong absorption peaks,which means that this film can be used as optical storage material matching the recording system with the laser source of 532nm.A result of about 600nm recording line with 21% reflectivity contrast is obtained at 15mW laser power with the 1m/s recording velocity.
