Job Description

LLNL’s Optical Fiber Laser Group is seeking a Postdoctoral Research Staff Member to participate in the research and development of fiber-based lasers (both continuous-wave and pulsed) and fiber-based sensors.  You will have hands-on experience with high power diode-pumped lasers, extensive experience in engineering or physics laboratories, and a completed doctorate degree in physics, electrical engineering, optics, chemistry, materials science, or a closely related field.  You will collaborate with other members of the Fiber Group to design, develop, and deploy advanced fibers and fiber-based lasers, in support of DOE and DOD-based missions.  This position is in the National Ignition Facility and Photon Science (NIF&PS) Principal Associate Directorate (PAD).

In this role, you will

  • Plan, execute, and analyze results of research and development laboratory experiments with a primary emphasis on scaling the average power and pulse energy of fiber-based lasers.
  • Collaborate with LLLNL scientists to design, build, and test novel fibers for lasers and sensors while also performing independent work as part of the team.
  • Participate in preparing proposal applications.
  • Specify and procure specialty laboratory equipment and supplies.
  • 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.
  • Prepare and conduct technical presentations for internal and external audiences.
  • Pursue independent (but complementary) research interests and interact with a broad spectrum of researchers.
  • Adhere to strict laboratory safety requirements.
  • Perform other duties as assigned.


  • PhD in Optical Fiber, Lasers, Optics and Optoelectronics, or related field or discipline such as Physics or Electrical Engineering.
  • Experience with laser sources, with emphasis on optical fiber-based lasers and nonlinear optics.
  • Experience in conducting laboratory experiments in one or more of the following areas: high energy ultrashort pulses, laser beam combination, diode-pumped fiber and solid-state lasers, nonlinear optics, ultrafast laser spectroscopy, optoelectronic devices.
  • Knowledge of and experience with optical fiber, laser science and optics, and/or basic statistics as it applies to the design of experiments and data analysis.
  • Ability to perform as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution including experience planning experimental campaigns.
  • Experience developing independent research projects, including publication of peer-reviewed literature.
  • Effective initiative and ability to work independently to meet deadlines.
  • Proficient verbal and written communication skills necessary to collaborate within a multi-disciplinary research team, author technical and scientific reports, publications, and papers, and deliver scientific presentations.

Desired Qualifications 

  • Experience with designing and/or building ultrashort pulse lasers.
  • Familiarity with state-of-the-art fiber and laser technologies (public, private, international R&D efforts).
