摘要：
A novel combination of a quasioptical antenna and a blazed grating which has been applied to gyrotron investigations at millimeter and submillimeter wavelengths is described. In this system the quasioptical antenna converts the conical beam from the gyrotron into a well-collimated, linear-polarized beam and the blazed grating acts as a frequency-selective demultiplexer. The system is very effective in separating the submillimeter wavelength output from GYROTRON V at the second harmonic of the electron cyclotron frequency from the nearby strong fundamental. This has enabled the study of mode competition between the second harmonic and the fundamental processes.
