Laser Science and Technology (LST)


The Laser Science and Technology (LST) division of the LCLS provides operational support for laser systems used in the LCLS photoinjector and experimental end stations. LST provides technical support for laser operations in the Accelerator Directorate (AD), Science Directorate, Stanford Synchrotron Radiation Lightsource (SSRL), and various research groups at Stanford and other national laboratories (LBL, ANL, LANL).

FACET laser

LST scientists conduct research programs aimed at increasing and improving laser capabilities for users and SLAC scientists in areas such as High Harmonic Generation (HHG), UV and shorter pulsewidth sources, THz source development, and X-ray optical cross correlation for improved pump/probe timing precision. They engage in collaborative research on laser-related programs, and guide the programs of PhD students focused on science involving lasers.

LST stewards laser safety at SLAC, working closely with the SLAC Laser Safety Officer to ensure consistent training and application of laser safety practices and policies throughout the facility.


The LST supports facilities across the SLAC and Stanford campuses. Current laser labs, facilities, and collaborations are shown in the table below.
