Abstract: The design and experimental verification of the launcher and mirror system of W band TE₆₂mode gyrotron quasi optical mode converter are presented. Based on the coupled mode theory, two order perturbation is used to design the launcher. The field distribution of the Gauss beam spot on the inner wall of the circular waveguide is obtained. The vector diffraction integral theory based on Huygens,s principle is used to optimize the mirror system of the optical mode converter. Simulation and calculation results show that the mode conversion efficiency of quasi optical mode the converter is 92.3%. Finally, a thermal measurement experiment is carried out to verify that the output mode is W band Gauss like mode.
