The remarkable effect of the two-component halogen donor mixture was obtained on the discharge-pumped XeF(B /yields/ X) laser using low-pressure (/le/2 atm) He and Ne diluted mixtures containing both F/sub 2/ and NF/sub 3/ donors. The laser output energy with the 2 atm He-diluted mixture containing the two halogen donors was increased by a factor of 2 over that with the conventional He/Xe/NF/sub 3/ mixture. Also with the atmospheric pressure Ne-diluted mixture containing two halogen donors, a laser energy enhancement was obtained of more than 70 percent over that of the Ne/Xe/NF/sub 3/ mixture. This important effect can be attributed to the increase of the laser extraction efficiency due to the enhancement of the net gain in terms of the laser parameters of small-signal gain coefficient, small-signal absorption coefficient, and gain saturation intensity estimated form a Rigrod's analysis.
