Abstract
The problem of line-hoppng in a short cavity, slab waveguide CO2 laser is studied by modeling of the laser signature and the experimental determination of laser spectra. It is shown that small increments of resonator length, less than 100 µm, significantly change the number of lines in the spectra and at a specific resonator length near 408.7 mm there is the possibility of single line operation. To reduce line-hopping and lock the laser to the 10P20 line, a 10th order, 2 dimensional grating has been laser engraved on one surface of the planar waveguide.
