The NICPB Helium station is the only one in the Baltic States and equips the University of Tartu and Tallinn University of Technology with liquid helium.
Nonlinear Spectroscopy femtosecond laser
The nonlinear optics lab employs a femtosecond pulsed excitation laser (PHAROS, Light Conversion UAB) combined with a optical parametric amplifier (Orpheus-HE, Light Conversion UAB) and second harmonic generator to produce < 150 fs pulses over a tunable wavelength range of 320 – 2600 nm, with an adjustable repetition rate ≤ 6 kHz. Typical pulse energies of 66 – 150 μJ are ideally suited for nonlinear optical spectroscopy techniques such as two-photon excited fluorescence (2PEF) in liquid samples.
