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 ..cap alpha../SUB o/ about 0.045 m/sup -1/ and I/SUB s/ about 0.44 kW/cm/sup 2/ for a Cl/sub 2/ flow rate of 1.4 X 10/sup -3/ mol/s with an I/sub 2/ flow rate of 4 X 10/sup -6/ mol/s. The dependences of the small-signal gain and saturation parameter have been also found on the Cl/sub 2/ flow rate. These behaviors are qualitatively explained by a simple two-level model.
