A Versatile CO2 Waveguide Laser For Application In Systems

The design and performance of a compact, sealed, high power CO2 waveguide laser in which the basic gain cell can support several different output formats is described. The laser can be operated in continuous wave (cw) mode or with frequency or amplitude modulation (FM or AM) depending on the cut of the CdTe intra-cavity crystal employed. Particular attention is given here to the FM performance of the device where the crystal is subjected to high intra-cavity powers.
