Interhalogen UV Laser on the 285 mm Band of CIF

Abstract A new UV-laser operating on the 285 nm band of ClF is reported. Fluorescence and laser oscillation on numerous vibrational and rotational lines has been observed following e-beam excitation of a Ne/F 2 /Cl 2 mixture. The upper laser level is probably formed in an ion recombination reaction of fluorine and chlorine ions.
