Custom-made terahertz spectrometer

(1) Spectrometer seeded by a femtosecond laser oscillator MIRA: for measurement of steady-state optical, dielectric and transport properties of solid and liquid samples in the range 0.1 - 3 THz.
(2) A setup powered by femtosecond laser amplifier SPITFIRE (1 mJ/pulse, 5 kHz repetition rate); optical pump - THz probe measurements of solids and liquids (0.2 - 2.5 THz); optical excitation using harmonic wavelengths (800 nm, 400 nm, 266 nm) or optical parametric amplifier (240 - 3000 nm)
Both spectrometers can be complemented by a cryostat or a furnace to cover temperatures 10 - 900 K.
