Laser Science Department (LAS)

The Laser Science Department (LAS) supports the development and operational deployment of optical laser systems for the LCLS user facility. We  facilitate the science mission of LCLS by interfacing with instrument teams and other SRD science departments to identify and fulfill experimental needs. This includes defining and executing strategic R&D projects to enhance our optical laser capabilities. We work closely with our colleagues in the Laser Engineering department on everything from day-to-day operations to large-scale upgrade projects. 

The Laser Science Department features four sub-groups each focused on aspects of our R&D portfolio. These include: 

  • the Advanced Laser Sources group, which focuses on high-power and high-energy laser source development
  • the UV-Vis Sources group, which specializes in frequency conversion and pulse manipulation techniques in the ultraviolet and visible spectral range
  • the Mid-IR & THz Source group, which exploits difference-frequency generation and optical rectification to generate mid-infrared and terahertz sources in conventional and novel nonlinear materials 
  • the Ultrafast Methods & Metrology group, which develops novel pulse delivery and characterization schemes, including time-of-arrival measurements with the LCLS x-rays

These research efforts involve collaboration with internal SLAC and Stanford groups as well as external institutions, and we host students and interns to foster connections with the community.
