Terahertz Spectroscopy System

Application of Terahertz waves (0.05–4THz) such as spectroscopy, sensing, imaging, and devices can be performed in the collaboration research.

We can offer the spectroscopy from terahertz region, infrared region
(FT-IR), to visible region. The range is 350nm – 6mm (0.2meV – 3.5eV ). Target: Semiconductors, insulators, magnetic materials,

biological materials, metamaterials…etc.

  • THz time domain spectroscopy (THz-TDS) can be performed.
  • THz imaging, Polarization measurement, Temperature dependence (4K-750K), Femtosecond or Picosecond Time resolved spectroscopy with THz and optical pulses,
    High intensity THz excitation measurements such as nonlinear optic phenomena.
  • Please contact us (M.Nakajima) about the measurement of THz wave.
