The authors have used transverse RF discharge pumping to produce CO lasers operating sealed off at temperatures near ambient and delivering powers of 37 W m-1. The peak efficiency was 15%, which is comparable with that obtained previously for lasers operating at liquid nitrogen temperatures. The design of the laser is described. The maximum multiline laser power obtained was 14 W with a coolant temperature of -28°C. This was for a gas mix of He:CO:N2:Xe:O2 (10:1:0.5:1:0.05) at 32 Torr. The emission spectrum consisted of P-branch transitions between the 15-14...8-7 vibrational bands of the CO electronic ground state. Amplitude modulation of the RF has been used to modify the emission spectrum and produce an amplitude modulation of the laser beam.
