Upconversion of laser radiation frequency in an oxygen-iodine laser

摘要

A gaseous mixture comprising iodine, oxygen and fluorine gases is circulated in a closed loop system 16 through a laser cavity 14. The gases in the cavity 14 are pumped by infrared laser radiation 12 from an iodine laser 10. A set of reactions occurs in the cavity 14 resulting in the production of excited, iodine monofluoride, molecules IF**(B)! which emit laser radiation in the visible spectrum.
