摘　　要：合成了 6个最大吸收波长在 1.0 6 μm附近的五甲川红外染料 (两个为不对称结构 )。结构经红外 ,H1核磁 ,元素分析表征 ,并测量了其 1,2 -二氯乙烷溶液的电子吸收光谱 ,范围在 10 52～ 10 95nm之间。它的 1,2 -二氯乙烷溶液对 1.0 6 μm波长的 Nd3 + :YAG激光进行锁模 ,全部锁模成功 ,波形稳定。脉宽为 2 6 .8～ 35ps。Six pentamethylidene IR dyes with a peak absorption wavelength at 1.06 μm (including two asymmetric dyes) were synthesized for a mode locking laser. The structure was demonstrated by IR, H 1NMR and element analysis. The absorption wavelength varied from 1052 nm to 1095 nm was tested in the solution of 1,2 dichloroethane. A stable laser pulse with a duration of 27~36 ps was observed by using the dyes. The dyes are successfully proved to be used as a collide pulse mode locking (CPM) dye for Nd 3+ ∶YAG lasers.
