Abstract:

Current progress toward the development of a tunable CO2 laser using an integrated optics approach is described. Design parameters for application as a local oscillator in an optical heterodyne receiver are emphasized with tunability to accommodate the large doppler offset. The integrated optics approach employs a nonuniform distributed iterative passive waveguide in close proximity to a planar active gas waveguide to form the resonant circuit. Backward wave Bragg diffraction coupling is employed between the active gas waveguide and the passive feedback waveguide. Transverse gas flow and transverse excitation are considered. The characteristics of nonuniform distributed feedback laser ring resonant circuits are analyzed employing a coupled mode approach. A 0.6 mm diameter bore capillary waveguide laser has been demonstrated.
