摘　　要：合成了吸收在红外域１２７０ｕｍ的红外调Ｑ、锁模染料，它的四氯乙烯溶液及聚甲基丙烯酸甲酯薄膜能对１０６４ｕｍ和１０７９ｕｍ激光进行满意的调Ｑ，脉宽为４～７ｕｓ。当用其二甲基亚砜溶液对１０７９ｕｍ和１３４０ｕｍ激光进行锁模时，显示出优良性能，锁模脉宽为３０～５０Ｐｓ。A novel infrared laser dye absorbing at 1270 urn was synthesized. The propertiesof switching and mode-locking for different laser were investigated. It can Q -switch 1064urn and 1079 urn lasers satisfactorily with tetrachloroethylene and PMMA film.The pulsewidths are 4-7 us. Iii s DMSO solution showes excallent ability in mode-locking 1079 umand 1340 um laser. The pulse-widths are 30-50 ps.
