CO2 waveguide TE laser

A specially constructed CO2 waveguide TE laser has several advantages over a conventional CO2 TE laser on account of its compact size, higher repetition rate, purity of polarization rate and so on. A five temperature model of the laser system is derived and then solved numerically. The relative numerical results are in close agreement with the experimental data. The laser output signature and polarization state are accurately predicted by this theory. Discrepancy exists between the theoretically predicted and measured output power which is due to the assumption of a uniform electrical discharge in the theory. Various preionization schemes could be employed to enhance the laser efficiency and produce more uniform discharges such that the theory would give a more accurate description of this particular laser device.
