Abstract
A COlaser that generates laser-radiation in just one emission band of a COgas-mixture has resonator mirrors that form an unstable resonator and at least one spectrally-selective element located on the optical axis of the resonator. The spectrally-selective element may be in the form of one or more protruding or recessed surfaces. Spectral-selectivity is enhanced by forming a stable resonator along the optical axis that includes the spectrally-selective element. The COlaser is tunable between emission bands by translating the spectrally-selective element along the optical axis.
