Lasing at 478.7, 484.7, 490.7, and 496.5 nm has been observed on the E..-->..A/sup 3/Pi (bound..-->..bound) band of the IF (iodine monofluoride) molecule in discharge-pumped He, Ar, CF/sub 3/I, and NF/sub 3/ gas mixtures. Oscillation was obtained using a stable optical cavity with output coupling mirror transmission of 0.2 and 92%. For a 99.7%-He, 0.2%-NF/sub 3/, and 0.1%-CF/sub 3/I (p/sub total/approx. =1540 Torr) gas mixture and Tapprox.92% (quartz flat), output pulse energies of approx.0.35 mJ in a approx.15-ns FWHM pulse (peak output power > or approx. =24 kW) were measured. Optimization of the cavity output coupling and increased Ar pressures in conjunction with the use of an attaching gas (to raise the discharge E/N) are expected to improve the output energy and, consequently, the overall efficiency of this blue-green laser.
