Abstract

PURPOSE:To check photodiscoloring of BDN and prolong Q-switching life by adding triplet elimination agent with the prescribed molar ratio to dithiolato complex system coloring matter with Q-switching action to laser light. CONSTITUTION:To make liquid coloring matter Q-switching composition for neodymium laser by adding triplet elimination agent with the prescribed molar ratio 10<-6>-5X10<-1>mol/l to the thiolato complex system coloring matter having Q-switching action to laser light with the prescribed molar ratio 10<-6>-10<-4>mol/l. Thereby bis-dimethylaminothiobenzyl-nickel will be used as dithiolato complex and 1,3,5,7- cyclooctatetraenanthracene or alpha-tocopherol will be used as triplet elimination agent. Further, 1,2-dichloroetane or toluene will be used as color solvent.
