The small-signal gain and saturation parameter of a transverse-flow CW oxygen-iodine laser have been experimentally obtained for the first time from output power measurements made as a function of the cavity losses without using a CW probe laser. These measurements typically yield a small-signal gain of 0.045 per m and a saturation parameter of 0.44 kW/sq cm for a Cl2 flow rate of 1.4 x 10 to the -3rd mol/s with an I2 flow rate of 4 x 10 to the -6th mol/s. The dependences of the small-signal gain and saturation parameter have been also found on the Cl2 flow rate. These behaviors are qualitatively explained by a simple two-level model. 18 references.
