A quasi-optical system consisting of a quasi-optical antenna and two ellipsoidal mirrors can convert the gyrotron output (TE15 mode, 354 GHz) into a gaussian-like beam. The waist size of the beam produced is adjusted by moving a second ellipsoidal mirror. The second mirror with focal length of 520 mm offers a tunable range from 2.0 mm to 5.4 mm, and those with focal lengths of 1190 mm and 2390 mm offer other tunable ranges from 5.1 mm to 12.9 mm and from 12.0 mm to 25.1 mm, respectively.
