Waveguide lasers utilizing a mixture of CO₂ isotopes

A. E. Bakarev, A. S. Provorov


Abstract: Waveguide lasers utilizing a mixture of CO₂ isotopes were investigated. Measurements were made of the gain for various lines of the isotopes ¹²C¹⁶O₂, ¹³C¹⁶O₂, and ¹²C¹⁸O₂ mixed with He. An experimental study was made of the dependence of the gain for the line of a specific CO₂ isotope on its concentration in a binary mixture. Various designs of a waveguide laser utilizing an isotope mixture were developed and some advantages and disadvantages were analyzed.
