ABSTRACT:
Disclosed is a pair of channel waveguide CO.sub.2 lasers formed in a common eramic block. Both discharge channels are DC excited for CW operation and share common mirrors at both ends. The laser cavity includes a Stark cell coupled via a window to one end of both discharge cannels and contains ammonia or deuterated ammonia. The Stark cell is further truncated by a grating opposite the window to provide an overall three mirror cavity configuration which permits predetermined laser line selection. The Stark cell, moreover, is configured to include two pairs of electrodes which permit independent voltage modulation of the two CO.sub.2 laser beams.
