In the Laser Dynamics Laboratory (LDL), state-of-the-art lasers are used in spectroscopic techniques to investigate the dynamics of energy relaxation and transformation, molecular mechanisms of the primary processes of photosynthesis, and charge and energy transport in nanomaterials.
The laser systems and other equipment present at LDL can also be used by researchers interested in studying the detailed changes in molecules or materials following linear or nonlinear laser excitation in the 100 femtosecond time scale or longer. The laser-induced changes can be followed by observing the optical absorption, fluorescence, Raman , or infrared spectra of the transients. The nonlinear properties of materials can be studied applying pico- or femtosecond laser pulses, where the laser power is high and the induced nonlinear signals are intense.
The systems and techniques at LDL may be divided into the following categories:
- Transient Optical Absorption Spectroscopy (~100 fs and slower)
