The laser laboratory is equipped with numerous laser sources and detection systems for a broad range of laser-based measurements including, laser-induced fluorescence, nanosecond fluorescence lifetime and transient-absorbance spectroscopy, laser-induced breakdown spectroscopy, and Raman and resonance Raman spectroscopy. The facility is housed in a dedicated 500 ft2 room with four optical tables.
