Job Description

We are seeking a Postdoctoral Researcher Member with expertise in nonlinear and ultrafast optics. You will have hands-on experience with high power diode-pumped lasers and extensive experience in engineering or physics laboratories.  You will team with research staff to conduct laboratory experiments on pulsed fiber lasers, as well as beam combining and system application of such lasers.  In addition, you will spend 25% time researching a related topic of your choosing.  This position falls within the Fiber Technology Group of the NIF&PS DOD Technologies Program (DODT) and is in the National Ignition Facility and Photon Science (NIF&PS) Principal Associate Directorate (PAD).

In this role you will 

  • Plan and execute laboratory experiments with a primary emphasis on scaling the average power and pulse energy of fiber-based lasers.
  • Perform independent work on a team with LLNL scientists to design, build, and test novel fibers for lasers and sensors.
  • Prepare and conduct technical presentations for internal and external audiences.
  • Pursue independent (but complementary) research interests and interact with a broad spectrum of researchers; can utilize up to 25% of your time on this; should be a topic that will help prepare you for a PI role in the future ideally.
