Abstract:

Ruby laser threshold damage data have been previously reported. Results indicate at least one order of magnitude difference in reported values. This paper reevaluates the threshold data in 20 eyes of rhesus monkeys from Q-switched ruby laser exposures in the range from one to 100 microjoules, with results described in terms of total energy delivered to the eye. The apparatus employed differed from that of previous investigators by the use of a TEMoo mode ruby laser in preference to a multimode laser. Author
