LCLS Laser Capabilities​

Experimental Laser Operations

The LAS division supports laser systems in experimental end stations during the course of LCLS runs. These systems undergo configuration changes for every beam time with parameters often changing during the experiment itself. To meet these requirements, LAS scientists safely manage and maintain a diverse set of commercial and specialty lasers.​

Supported Instruments


CXI - Coherent X-ray Imaging

MEC - Matters in Extreme Conditions

MFX - Macromolecular Femtosecond Crystallography

TMO - Time-resolved AMO

TXI - Tender X-ray Instrument

XCS - X-ray Correlation Spectroscopy

XPP - X-ray Pump Probe

MeV-UED - MegaelectronVolt Ultrafast Electron Diffraction

Pump-Probe Experiments

Many pump-probe experiments utilize an LAS laser as a drive. After the laser produces a transient state, X-rays probe the sample at various time delays to resolve the dynamics.

Injector Laser Operations

Fundamental to the Linac Coherent Light Source is the Injector Laser system, which provides ultrashort pulses of UV light to produce ultrashort electron bunches from the Cu cathode. The LAS is responsible for the operation of the LCLS Photo-Injector lasers - two identical systems available 24/7. Below is a schematic of the layout of the two systems in the injector laser lab.
