Studies of E-Beam Pumped Molecular Lasers

Abstract

The authors have observed intense band emissions between 340 nm 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/N2 mixture as a calibration, the authors have measured the fluorescence yield in this wavelength region to be 70 plus or minus 24%. From this, an over-all fluorescence energy efficiency of 13 plus or minus 4% was computed. Based on these observations, it is suggested 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/N2 second positive laser.
