【摘要】We introduce an asymmetrical mirror design to a 140 GHz TE22,6 quasi-optical (QO) mode converter system to correct the asymmetry of the beam's field distribution caused by the Denisov launcher.By such optimization,the output beam with better symmetrical distribution is obtained at the system's output window.Based on the calculated results,the QO mode converter system's performance is already satisfying without iterative phase correction.Scalar and vector correlation coefficients between the output beam and the fundamental Gaussian beam are respectively 98.4％ and 93.0％,while the total power transmission efficiency of the converter system is 94.4％.The assistance of optical ray tracing to the design of such QO mode converters is introduced and discussed as well. 【总页数】6页(75-80) 【关键词】
