Gain and absorption measurements of electron beam pumped, high Kr concentration KrF gas mixtures
Gain and out-of-band absorption measurements are made of electron beam pumped KrF laser mixtures (Ar diluent) with 4--99.6% Kr concentrations. The average pump rate is maintained at roughly-equal120 kW/cm/sup 3/ by adjusting the total pressure of the mixtures to compensate for the different electron stopping powers of Ar and Kr. The F/sub 2/ number density is also kept constant at 8.9 x 10/sup 16/ cm/sup -3/. Measured small-signal gains (g/sub 0/-..cap alpha..) are 3.8%/cm at 4% Kr, 3.3%/cm at 50% Kr, and 3.2%/cm at 99.6% Kr. The out-of-band absorptions (261 nm) are 0.43%/cm at 4% Kr, 0.74%/cm at 50% Kr, and 0.87%/cm at 99.6% Kr. Our computer model agrees with the results and predicts in-band absorptions (248 nm) of 0.29%/cm at 4% Kr, 0.44%/cm at 50% Kr, and 0.52%/cm at 99.6% Kr.
