Abstract : The program is an exploratory study on waveguide gas lasers in general, with an emphasis on waveguide CO2 lasers. The goals of the program were to investigate the operating parameters of waveguide gas lasers, to demonstrate single mode operation of a CO2 waveguide laser over the pressure broadened linewidth, to mode lock the CO2 waveguide laser, and to study mode control of waveguide lasers. Experiments on frequency tuning of the waveguide CO2 laser were performed. An extensive theoretical treatment has been performed on resonators for waveguide lasers. Using a matrix diagonalization technique, the resonator losses and resonator modes for waveguide resonators have been determined. Specific resonator configurations were found which are specifically designed for high transverse mode selectivity.
