Job Description

We have multiple openings for Laser Science Postdoctoral Researchers to participate in the research and development of laser systems for isotope separation.  These systems require a range of lasers – solid state and other – with important challenges in bandwidth, wavefront, timing, and alignment control.  You will team with members of LLNL’s laser and separation teams to design, develop, and deploy lasers in support of Department of Energy and Department of Defense-based missions.

You will ideally have a background including hands-on experience with high power pulsed lasers as well as a doctorate degree in physics, electrical engineering, optics, chemistry, materials science, or a closely related field.

These positions falls within the DOD Technologies Program (DODT) of the National Ignition Facility and Photon Science (NIF&PS) Directorate.

In this role, you will

  • Plan and execute laboratory experiments with a primary emphasis on scaling the average power, pulse energy, and transport and delivery of LIS laser and optical systems.
  • Perform independent work on a team with LLNL scientists to design, build, and test diagnostic and control systems for lasers and sensors.
  • Prepare and conduct technical presentations for internal and external audiences.
  • Work within a dynamic team, including senior and junior scientists and engineers, to coordinate resources, plan experimental campaigns, document research, perform training/mentorship, provide deliverables, publish papers in peer-reviewed journals, and present results.
  • Pursue independent (but complementary) research interests and interact with a broad spectrum of researchers.
  • Participate in preparing proposal applications.
  • Specify and procure specialty laboratory equipment and supplies.
  • Adhere to strict laboratory safety requirements.
  • Perform other duties as assigned.


  • Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • PhD degree in physics, electrical engineering, optics, chemistry, materials science, or a closely related field.
  • Understanding of, and experience with, optics, lasers, and laser science.
  • Experience planning experimental campaigns including ability to perform as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution.
  • Ability to work independently and meet deadlines.
  • Effective initiative and interpersonal skills ability to work in a collaborative, multidisciplinary team environment.
  • Proficient verbal and written communication skills necessary to interact with a multi-disciplinary research team, author technical and scientific reports, publications, and papers, and deliver scientific presentations.

Qualifications We Desire

  • Experience with laser sources, with emphasis on high average-power pulsed lasers.
  • Experience in engineering or physics laboratories, including data acquisition and control system development/utilization.
  • Familiarity with state-of-the-art laser technologies such as solid-state fiber-based lasers.
