Flashtube-Pumped Dye Laser with Multiple-Prism Tuning

A four-prism tuning system has been built and tested in a flashtube-pumped rhodamine 6G dye-solution laser. Equations for calculating reflection losses and prism dimensions are given, and performance characteristics of the tuned laser are presented. The half-power points of the tuning range were 571 nm and 615 nm, and the output bandwidth at peak power was 0.17 nm at half-maximum. The energy output at 595 nm was 0.14 J.
