Abstract

The transmission and input end heating of hollow-glass waveguides are greatly affected by the launch conditions of the input laser energy. A theoretical discussion is given on the effect of coupling conditions from a carbon-dioxide laser and its effect on waveguide performance. It is shown that the optimum coupling for maximum transmission is not necessarily equivalent to optimum coupling to the lowest- order HE₁₁ mode. It is also shown that the input end heating of these waveguides can be reduced substantially with minimal effect on transmission if the waveguide bore size is large.
