The possibility of an efficient tunable molecular iodine laser near 340 nm
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/N2 mixture as a calibration, we have measured the fluorescence yield i...

Summary: | 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/N2 mixture as a calibration, we have measured the fluorescence yield in this wavelength region to be 70±24%. From this we computed an over-all fluorescence energy efficiency of 13±4%. 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/N2 second positive laser. |
