Time-resolved Spectroscopy using optical and THz radiation
An optical pump/THz probe technique called time-resolved THz spectroscopy (TRTS) is used to explore systems where a visual excitation triggers a change in the far-infrared absorption properties on a timescale of a few picoseconds.
Our Ultrafast Photonics Lab is building TRTS system is built around a regeneratively amplified Ti:sapphire laser that generates 100-fs, 800-nm pulses with a 1 kHz repetition rate. Two beams are separated from the output: one for the pump beam and the other for THz generating and detecting. THz radiation is produced in a ZnTe(110) crystal using optical rectification, and it is detected in a second ZnTe(110) crystal through free-space electo-optic sampling. At the same spatial and temporal location as the pump beam, the THz beam is focussed onto the sample. Figure provides a schematic representation of our set-up.
