Abstract : The patent discloses a technique for stabilizing the frequency of a gas laser at a desired value which uses an apparatus having an absorption cell containing a gas and a pair of plates therein through which the output of the laser is twice passed. An RF electric field and an AF field are applied to the gas in order to induce DC absorption sidelobes therein. By detecting whether the output radiation has been absorbed by the gas the laser output can be locked to a desired frequency.
