Company Overview
Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.
We are dedicated to fostering a culture that values individuals, talents, partnerships, ideas, experiences, and different perspectives, recognizing their importance to the continued success of the Laboratory’s mission.
Position Summary We are seeking a
Laser Modeling Physicist
within our Laser Science and Systems Engineering Program to participate in the research, development, and modeling of advanced solid state laser technology, and high energy laser design for Inertial Confinement Fusion (ICF). This work will take place within the National Ignition Facility & Photon Science (NIF&PS) Directorate, home to the world’s most energetic laser.
Pay Range $140,700 - $214,032 Annually (SES.2 level) or $168,780 - $214,032 Annually (SES.3 level). Salary will not be below any applicable local minimum wage.
Responsibilities
Contribute to the development of advanced laser physics and nonlinear optics models coupled with the existing LLNL beam propagation code VBL++ (Virtual Beam Line) running on both single and extreme parallel-processor high performance computers with the goal to optimize designs for NIF & Next Generation of High Energy Density (NG-HED) facilities and ICF-IFE architectures.
Collaborate with the Computer Science team and provide solutions to experiments that will validate the physics captured in the thermo-mechanical codes used to predict the impact of thermal and mechanical effects on beam quality (wavefront and polarization) at the component level and at the system level, when coupled with VBL++.
Work within a dynamic team environment to document research; publish papers in peer‑reviewed journals, and present results within the DOE community and at conferences.
Utilize independent judgement along with scientific methods and techniques, contributing to the fulfillment of research and development in one or more of the following areas: Modeling and experimental testing of optical parametric short pulse amplifiers, chirped pulse amplification, solid state laser materials science, high‑speed electro‑optics devices, atmospheric beam propagation, frequency conversion and non‑linear optics, and design of advanced laser architectures for NG‑HED in support of National Security missions.
Perform other duties as assigned.
Additional Job Responsibilities (SES.3 Level)
Utilize in‑depth analysis, contributing to the development of experimental campaigns to enhance NIF performance.
Conduct technical tasks for advanced laser models using innovative methods and subject knowledge. Work includes expansion beyond the state of the VBL++ art (e.g., related to nonlinear stimulated processes, or nonlinear optics interaction in non‑paraxial regime).
Qualifications
Ability to secure and maintain a U.S. DOE Q‑level security clearance which requires U.S. citizenship.
Ph.D. in Optical Sciences, Physics, Engineering or Mathematics or the equivalent combination of education and related experience.
Comprehensive knowledge in experimental physics in one or more of the following areas: solid state lasers, laser cavities, short pulse laser technology, frequency conversion, non‑linear optics, crystal optics, atmospheric beam propagation, thermo‑mechanical finite‑element calculations interfaced with optical performance.
Comprehensive problem solving, decision making, and analytical skills, necessary to anticipate, analyze, advise, recommend, and approve appropriate actions and implement solutions to moderately complex to complex issues or laser designs.
Broad experience with MATLAB, Python and/or similar scripting and data analysis tools and the ability to write beam propagation, nonlinear optics, or amplification codes.
Broad experience and comprehensive knowledge in signal and image processing of laser diagnostics signals.
Broad experience with scientific research and development.
Proficient written and verbal communication skills to collaborate effectively in a team environment and present and explain technical information within a collaborative, multidisciplinary team.
Additional Qualifications (SES.3 Level)
Advanced knowledge and hands‑on experience in short‑pulse laser physics and nonlinear optics as applied to laser applications and operations.
Advanced problem solving, troubleshooting, decision making, and analytical skills necessary to anticipate, analyze, advise, recommend, and approve appropriate actions and implement solutions to complex issues.
Advanced experience with scientific research and development.
Ability to augment laser physics, nonlinear optics modeling to increase VBL++ modeling capabilities.
Qualifications We Desire
Knowledge of laser architectures, technological limitations, and machine safety aspects of large, distributed, high energy and high peak power laser facilities.
Experience in planning and directing work with technical objectives, estimating effort, and setting milestones.
Experience in the development of scientific software (ideally C++) applied to laser physics and nonlinear optics problems.
