  • Abstract
    We improved the spectral accuracy in asynchronous-optical-sampling THz time-domain spectroscopy (ASOPS-THz-TDS) by sweeping the mode-locked frequency in dual fiber lasers. We confirmed from THz spectroscopy of low-pressure water vapor that the achieved spectral accuracy largely exceeds the spectral resolution in ASOPS-THz-TDS.
