Note (General): Accurate measurement of gyrotron frequency has been carried out by using a far-infrared (FIR) molecular laser as a reference. Highly stable operation of a FIR laser enables us to make the resolution of frequency measurement so precisely that both the frequency width Δf and the frequency fluctuation level δf can be studied within the accuracy of 1 kHz or less. When our submillimeter wave gyrotron operates in cw mode, the observed frequency width Δf is around 2 kHz and the fluctuation level δf 10 kHz. Such an accurate measurement is a useful tool for development of high quality gyrotrons with stable frequency.
