Research Abstract

We have developed a high-accuracy and high-resolution teraheltz(THz) electromagnetic wave frequency counter based on THz standard frequency comb, which consists of many accurate frequency lines extending from microwave region to THz region, utilizing our previously developed "multifrequency heterodyning photoconductive detection". The system adopted a fiber laser as a light source to be small-size, stable and robust instrument for a practical use. Measurement precision of 2.4*10^<-1>, bandwidth of 1THz and minimum power limitation of a few hundreds of nanowatt have been achieved.
