Optical gain was observed on the B to X transition of the Cs(2+)F(-) ionic excimer molecule at 185 nm. The excimer was produced by photoionization of CsF vapor using a laser-produced plasma source. An average net gain coefficient of 0.3 per cm was measured for 7 Torr of CsF and a 225 mJ pump laser.
