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.
