CLAS: Ultra Fast Laser Facility

Equipment/facility: Facility

    United States

Description

This multi-user facility is specialized in the development and application of time-resolved laser spectroscopy to chemical, biological and material research. It provides advanced laser technologies and instruments for spectroscopic and imaging measurements to observe chemical reactions in real time with temporal resolution down to femtosecond time scales and spatial resolution and sensitivity to the point where single molecule signals are detectable. The femtosecond spectroscopy part of the facility consists of several femtosecond Ti:Sapphire lasers coupled with transient absorption and fluorescence spectrometers, providing users with a broad range of excitation and probe wavelength for kinetic measurements. The single molecule microscopy part of the facility consists of both pulsed and CW lasers, confocal microscopes and single photon counting detection systems.
