Abstract

The study of output laser beam shape as a function of losses, internal diameter, off-center coupling and scattering is presented in this paper. The conditions where the beam shape has good correlation with the source beam shape were found (low losses, center alignment coupling and low scattering). A theoretical model of the mechanism of propagation of the radiation through the hollow waveguides was developed and the conditions under which the shape of beam is changed was calculated. Good agreement between the theoretical and experimental results was found.
