THz Time-Domain Spectrometer (TDS)

The CAS laboratories is home to a THz Time-Domain Spectrometer (TDS1008, BATOP).

The TDS uses an ultrafast laser (λ=785 nm, Δtpulse=100 fs) which provides, in combination with high-performance photo-conductive antennas, a large spectral bandwidth (1–5 THz) and a high dynamic range (4 orders of magnitude) in signal. It is capable of pulse pump-probe delays up to 650 ps, and is thus compatible with a wide range of optically-active samples.

The instrument has built-in mounts for small samples, and it can also be interfaced to a closed cycle, ultra-low vibration cryostat (CS210SFg-GMX, Advanced Research Systems).
