Abstract

First experiments on fundamental band CO lasing in sealed-off cryogenically cooled slab facility with RF discharge excitation were carried out. Repetitively pulsed and CW modes of RF discharge excitation were studied. The laser output characteristics for different slab geometries were compared. Average output power achieved 12 W. Lasing efficiency came up to ~14 %. The output laser spectrum was observed within wavelengths range 5.08-5.34 &mgr;m. Stable lasing was obtained for more than one hour. Preliminary study of single-line lasing was carried out.
