Carbon dioxide laser signature phenomenon in a self-calibrating spectral servomechanism

A servomechanism for identification of the CO2 laser lines, and searching desired laser signatures is elaborated. The laser signature is used as a standard for calibration of the servomechanism. Algorithms for process automation are find. The system can be used in servo-loop mechanisms for stabilization of the laser operation to a chosen emission line. The method can be expanded using different isotopes of carbon, and/or oxygen molecules in the laser medium. Some applications of the method are suggested.
