The concept of higher order free space modes, gaussian-like beam modes can be applied to
efficiently transport the power generated by a gyrotron for technological applications. Waveguide modes
can be coupled properly to higher order gaussian modes. These modes can be guided by an optimized
higher order beam waveguide to the final experiment.
A family of optimized non linear horn antennas is investigated in order to maximize the coupling
between the guided output modes of a technological gyrotron and the free space modes. The numerical
computations show very favourable coupling to higher order gaussian modes, with a conversion effiencies
of about 99.8%.
