Our group is studying light-matter interaction effects in materials ranging from polar crystals to molecular organic crystals, individual molecules, polymers, and organic light emitting diodes. We use picosecond-long laser pulses with a wavelength that can be set over the whole visible and infrared spectral range between the wavelengths of 400 nanometers and 2 micrometers to create and detect various kind of excitations in these materials, including nonlinear optical effects, photocurrents, and charge-transport.
