Tunable 10Micron Laser,An Integrated Optics Approach to Infrared Gas Lasers,

摘要

The further development of a tunable CO2laser employing an integrated optics approach to its construction is discussed. The opposite laser design parameters emphasize application as a local oscillator for a tunable optical heterodyne receiver. 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 is employed between the active gas and the passive feedback waveguide. Transverse gas flow and transverse excitation are considered as opposed to the longitudinal configuration of a capillary waveguide laser. The incorporation of a traveling surface elastic wave (Rayleigh) collinear and within the passive feedback waveguide to alter the dispersion is the approach considered to achieve the wide unambiguous tuning range.
