摘要
合成了６ 种五甲川吡喃鎓盐染料，通过红外光谱、核磁共振氢谱及元素分析确证了其结构． 研究了其电子吸收光谱及其在Ｎｄ３ ＋ ：ＹＡＧ激光器上的锁模性能． 结果表明，染料在１ ，２二氯乙烷溶液里最大吸收波长在１０５２ ～１０９５ ｎｍ 之间，６ 个染料全部锁模成功，脉宽为２８ ～３５ ｐｓ，锁模情况比镍络硫代双烯型染料ＢＤＮ 好．
Six pentamethine pyrylium dyes have been synthesized and characterized by IR, 1H NMR and elemental analysis. Their electronic absorption spectra and characteristics of mode locking have been studied. The λ max of the dye solutions are found to be in the range of 1052～ 1095 nm and the pulse widths within 28～36 ps. They were also found to be useful as collide pulse mode locking(CPM) dye for Nd 3+ :YAG laser and mode locking dyes for Nd 3+ :YAG, better than BDN.
