A substantial improvement in the specific laser output power (up to 30%) and efficiency (up to 50%) of a radio frequency (rf) excited slab CO[sub 2] laser with a distributed gold catalyst is observed when a large amount of CO (more than 60% of CO[sub 2] concentration) is added to the laser gas mixture. A maximum output power of 160 W with an efficiency of 17% was obtained from a laser with an active volume of 2x15x370 mm[sup 3]. Gas mixtures with a high CO concentration combined with a distributed gold catalyst also accelerate the start-up time of rf pumped CO[sub 2] lasers considerably. © 2000 American Institute of Physics.
