Beam profile dependence on conditions of propagation through hollow flexible IR waveguides

A theoretical ray model of IR radiation propagation and delivered beam shape profile of hollow flexible waveguides was developed. Experimental studies of attenuation of coupled CO 2 MID-IR laser (wavelength-10.6 micrometers ) and the influence of losses, internal diameter, coupling and scattering on the shape of propagated beam were performed. The theoretical and experimental results have shown a good concordance.
