Dependencies of LIF signal on flow rate and on flow rate through the discharge generator and jet type iodine injector. The pressure inside the generator was 20 Torr and the discharge current was 1.2 A. About 50% of had dissociated.

Decay rates vs at its maximum. Two upper sets of points ( rake and rake) were obtained with the rake nozzle bank, varied from 0.5% to 1.8%. Two lower ( jet and jet)—with the jet type injector. The open circles on the plot are for the experiments with the discharge on. The open triangles are for the constant flow and different discharge currents. These points illustrate that gas heating in the discharge has no visible effect on the laser medium.
