Abstract:

This report has been prepared for the timely presentation of information on calculational procedures for dye laser parameters and is released at the working level. The methods used here are fairly general and can be applied to other laser systems as well. Further, the report provides an intuitive basis for reasoning about laser phenomena. Although several textbooks give elementary treatments to calculations of laser thresholds, power output, and gain saturation, none of these is really adequate for the specific case of dye lasers for two reasons the textbooks calculate thresholds in terms of spontaneous lifetimes, which in dyes are very short and hard to measure, and the textbooks fail to give a feel for the microscopic atomic events which occur in the laser because they perform the entire calculation in terms of macroscopic quantities. Therefore, for this study it was decided to treat the laser problem in terms of experimentally measurable atomic emission and absorption cross section. Author
