Optically pumped Iodine monofluoride B3Π(O+)→X1Σ+ laser

Abstract

An optically pumped iodine monofluoride laser operating on the B3Π(O+)→X2Σ+ system has been demonstrated. Ground-state IF was produced by the reaction of I2+F2 and subsequently excited with a high-energy, broadband dye laser. Lasing was observed on the (2,10), (3,11), (4,9), and (4,10) transitions covering the wavelength range 7200–6500 Å.

Hyperfine constants of bromine and iodine monofluoride

“…There has been considerable recent interest in using the interhalogens, 19,20 particularly ClF ͑Refs. 21 and 22͒ and IF, [23][24][25][26][27] for lasers in the visible and UV regions.…”

Optical gain on the I2 (B3Πo+→X3Σg+) system produced by a visible wavelength diode laser

“…In particular, argon ion and dye laser excitation of selected halogen and interhalogen molecules, e.g., I 2 , 1-8 Br 2 , 9 and IF 10 have resulted numerous pulsed and cw lasers with extensive, but discrete, tuning capabilities. In these prior studies, large frame argon ion and both pulsed and cw dye lasers were required as pump sources.…”

“…The recorder was interfaced to a microcomputer (Cromemco Z-2D) via a CAMAC crate system. This data acquisition system was programmed to record either real time fluorescence decay curves or 4,4 systemwasprgramme deca excitation spectra. In the former mode, the decay curves captured by the transient recorder were signal averaged by the computer between laser pulses.…”
