Propagation losses at 10.6 microns in hollow-core rectangular waveguides for distributed feedback applications
Abstract
The theoretical losses of various materials and possible waveguide configurations applicable in hollow-core distributed feedback lasers at 10.6 microns are discussed. Waveguide materials such as gold, BeO, glass, and germanium are analyzed. It is shown that by using gold for the top and bottom waveguide regions with BeO for the side walls, loss as small as 1.19 dB/m can be obtained with a cross-sectional dimension 0.1 x 0.8 mm. Loss calculations indicate the feasibility of constructing a conventional electric discharge waveguide laser for DFB operation at 10.6 microns.
