At the moment we are building passively the phase stabilized Fourier-transform 2D electronic spectroscopy setup, in the new laboratories of the Department of Chemical Physics. Three broadband femtosecond pulses (20-40 fs) will be used to excite sample and the resulting three pulse photon echo signal will be characterized in amplitude and phase by spectral interferometry by heterodyning it with a forth, so called local oscillator pulse.
