Title: The possibility of an efficient tunable molecular iodine laser near 340 nm

Abstract

We have observed intense band emissions between 340 and 344 nm from electron-beam-excited mixtures of high-pressure argon gas and iodine vapor. This emission appears to be from molecular iodine. Using the 357.6-nm band from an Ar/ N$sub 2$ mixture as a calibration, we have measured the fluorescence yield in this wavelength region to be 70plus-or-minus24%. From this we computed an over- all fluorescence energy efficiency of 13plus-or-minus4%. Based on these observations, we suggest the feasibility of an efficient high-energy electron- beam-pumped argon-iodine laser. The gain of such an argon-iodine laser should be comparable to that of the Ar/N$sub 2$ second positive laser.
