M Squared Lasers Sprite 30 fs, 800 mW Ti:Sa Laser
This turn-key mode-locked Ti:Sa laser operating at 800 nm that provides 30 fs pulses at 100 MHz with average output powers of 800 mW. The system is set up in a time domain system using non-linear crystals and photoconductive antenna to allow THz spectroscopy between 60 GHz and 5 THz. The system is being used for gain measurements of THz quantum cascade lasers.
Edinburgh Instruments Far Infrared Laser
This laser delivers CW output between 0.25 and 7.5 THz with output powers up to 180 mW at 2.54 THz (the power is dependent on the molecular line being used).
Edinburgh Instruments MTL3 TEA CO2 Pulsed Laser
This laser delivers average power up to 50 W in ns pulses (up to 150 MJ per pulse) and is used for optical pumping at the CO2 wavelengths between 9.1 and 10.9 µm.
mm-wave and THz FTIR
Two vacuum Bruker 66 vs Fourier Transfor Infra Red (FTIR) spectroscopy systems with a QMC liquid He cooled Si-bolometer and beam splitters that allow power measurements, polarisation and spectra to be obtained between 60 GHz and 18 THz (about 16 µm).
Mid and Near Infrared FTIR
A Bruker Vertex 70 Fourier Transfor Infra Red (FTIR) spectroscopy systems that allows power measurements, polarisation and spectra to be obtained between 900 nm and 18 µm.
