Status of CO 2 isotope lasers and their applications in tunable laser spectroscopy

The use of CO 2 isotopes can provide a manifold expansion of the usable frequency range of sealed-off CO 2 lasers. Determination of the frequency, gain, and saturation parameter of the various CO 2 isotopic laser transitions will be discussed. Design considerations for constructing CO 2 isotopic lasers and selected applications will be presented.
