Abstract :
We developed a frequency difference stabilizer for an optically synchronized dual-channel terahertz-signal generator. The stabilizer reduces the amplitude fluctuation in spectrometer signal, enabling us to instantaneously observe the spectra, whose absorption characteristics change rapidly with time.
