Paper Abstract

A 30 cm long waveguide made of two specularly reflecting water-cooled brass plates was built for use with a 3 kw CO2 laser beam focused with telescopes having numerical apertures ranging between f/7 and f/150. In order to improve the collection efficiency a V-shaped throat was used as input section. The coupling coefficients of a Gaussian beam were calculated for different illuminations by using simple expressions derived from the uniform asymptotic theory (UAT) of diffraction . Essential to this approach it was to simulate the beam as a wave radiated by a source located at a complex point.
