SLAC National Accelerator Laboratory’s Linac Coherent Light Source (LCLS) Directorate seeks a Research Associate to support the development of high average power ultrafast lasers for the next generation of X-ray free-electron laser experiments.

SLAC National Accelerator Laboratory is a multipurpose laboratory for astrophysics, photon science, accelerator and particle physics research, operated by Stanford University for the US Department of Energy. The Linac Coherent Light Source (LCLS) is the world's first hard X-ray free electron laser (FEL), and operates as a user facility for a global community of scientists, providing ultrashort, ultra-bright pulses of X-rays to seven experimental instruments focused on specific areas of science, probing the structure and dynamics of matter at the atomic spatial scale and femtosecond timescale. Femtosecond optical lasers are an integral part of many of these experiments, and the LCLS Laser Science and Technology (LST) Division is responsible for developing and support cutting-edge laser systems for groundbreaking scientific research at  LCLS. The next generation free electron laser at SLAC, LCLS-II, will be based on superconducting accelerator technology, enabling operation at repetition rates up to 1 MHz with initial operation at 100 kHz. Optical pump/probe laser systems will need to be developed at matching repetition rates.

The Research Associate is expected to work on development of a high average power R&D laser amplifier system based on OPCPA (Optical Parametric Chirped-Pulse Amplifier) technology to achieve >1 mJ, 15 fs, >100 W, 800nm. Development includes testing of the current R&D system at a center wavelength of 1.5 and 3.2 μm, develop beam transport solutions for high average power beam to the LCLS-II end-stations and secondary sources at high average powers (e.g. tunable operation of an IR version of the OPCPA, THz generation, harmonic generation). An improved production system of the R&D amplifier is expected to be operational at LCLS-II at “first light” in the year 2020. This position will report to the Department Head for the Lasers in LCLS Science Department with functional accountability to the principal investigator of the high average power laser R&D project.

*Note:* The position is initially a two-year term with the possibility of renewal.
