Parametric study of a slab first-overtone carbon monoxide laser was performed. The compact slab first-overtone CO laser with active volume 3x30x250 mm3 was excited by a repetitively pulsed capacitive RF discharge (81 MHz or 60 MHz) with pulse repetition rate 100-500 Hz. The laser electrodes were cooled down to 120 K. Gas mixtures CO:O2:N2:He with different component contents at gas pressures 15-22 Torr were used. Two laser resonator mirrors sets were used in the experiments on multiline lasing. More than 100 spectral lines within the spectral range ~2.5-4.0 μm with maximum single line average output power 12 mW were observed. Total output power of the slab firstovertone CO laser came up to 0.3 W, with maximum laser efficiency 0.5%. Special details of long time output laser power behavior are discussed.
