Many fundamental processes in materials, such as charge carrier photogeneration, transport, relaxation, and recombination occur over picosecond time scales. In addition, the characteristic energy scales associated with a given process can vary greatly between different material systems. In order to better understand such ultrafast processes in materials and to study their effect in device structures, it is therefore essential to use ultrafast laser techniques that can excite and probe samples over a wide range of wavelengths with sub-picosecond time resolution. In the Ultrafast Spectroscopy Lab, we use high power ultrafast laser sources to study ultrafast phenomena in materials and devices, providing valuable insight into the nature of new materials and the ultimate switching speeds and response times of devices.
