Abstract
A continuous wave optically pumped iodine monofluoride laser operating on the $B^{3}\pi(0^{+})\to X^{1}\Sigma(0^{+})$ system is described. Laser operation was achieved on a series of rotational lines originating from $v^{\prime} = 2, 3, 4$, and 5. By tuning the dve laser pump source over a single rovibronic line, spectral structure was produced on the IF laser output that ws analyzed and found to be consistent with the hyperfine structure of the B state of IF. The nuclear quadrupole coupling constant,$-e0_{m}0$, and the spin-rotation constant, $C_{I}$, were determined as $(443 \pm 70)$ MHz and $(34 \pm 6)$ kHz, respectively, for the $(v^{\prime}, J^{\prime}) = (3, 19)$ state in IF(B).
