Abstract :
We observed detailed spectrum of THz frequency comb by extending the measured time window of the pulsed THz electric field up to ten pulse periods with asynchronous-optical-sampling THz-TDS (ASOPS-THz-TDS). Observed spectrum of THz comb mode has a linewidth of 5.6 MHz and a frequency interval of 56 MHz.
