It is shown that the optimum ratio between the main components CO2:N2:He of the active medium of continuous‐wave electric‐discharge CO2 lasers depends on the temperature of the active medium. Continuous‐wave CO2 lasers can operate effectively at high temperatures of their active medium (T ∼ 1000 K) if in their composition the fraction of N2 molecules is increased as compared to the fraction of CO2 molecules (CO2:N2 < 1:15) and the fraction of He atoms is decreased (He < CO2 + N2).

    A method is described for stabilization of a cw CO2 laser by locking it to a modulated external cavity which is locked to a HeNe reference laser. This avoids the necessity of modulating the CO2 laser. Stability values of a few tens of kHz on the microsecond and minute time scales have been achieved.
