Abstract
A continuous-wave CO chemical laser, developed at DREV, produced very feeble power of a few milliwatts. By the addition of vibrationally cold CO and by certain refinements of the apparatus, the power was increased by nearly two orders of magnitude to ca 300 mw. The effect on the laser power of the addition of CO was caused by selective depopulation of lower lasing levels of the vibrationally excited CO. Similar power enhancing effects were observed for other admixed gases whose vibrational spacings were nearly resonant with the lower vibrational level spacings of the CO molecule.
