Institute for Ultrafast Spectroscopy and Lasers







The research at IUSL is centered on photonics, the science and technology of generating and harnessing light and other forms of radiant energy whose quantum unit is photon. Photonics encompasses the generation, propagation, deflection, amplification, manipulation, detection, and various applications of light. The advent of lasers in the 1960’s may be considered to be the precursor of the photonics era. Time-resolved optical spectroscopy, one of the major areas of photonics, has evolved from millisecond to femtosecond in resolution during the past 30 years. The research at IUSL has always been on the forefront of this evolution and many crucial steps in this evolution have occurred at IUSL. IUSL researchers take pride in being able to identify emerging photonic technology areas, and to be among the pioneers in developing those areas.
