Waveguide CO2 laser utilizing the sequence bands obtained by transverse rf excitation through a dielectric

An investigation was made of a waveguide CO₂ laser excited by a transverse rf discharge through a dielectric, with no circulation of the gas mixture. The emission frequency was tuned by a diffraction-scattering film in the laser resonator. Lasing was due to the [00⁰2–10⁰1, 02⁰1]_I, II sequence transitions of CO₂. The energy characteristics of the laser operation are given for different gas mixtures.
