This position is within the Laser Systems Engineering and Operations (LSEO) division within the Engineering Directorate.
- Conduct advanced research into novel approaches for enhancing laser diode technology.
- Design and execute hypothesis-driven experiments on diode lasers and associated optical and electronic components.
- Design, build, and commission new diagnostics for kW-class semiconductor diode laser packages, including but not limited to optical and mechanical alignment, signal processing, and data acquisition.
- Develop novel tools for material defect characterization and execute experiments to determine the role of defects in diode laser performance.
- Analyze and interpret optical, electrical, and thermal performance data, including the development and use of models when necessary, to draw conclusions and plan experiments.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Publish research results in peer-reviewed scientific or technical journals, and present results at external conferences, seminars, and/or technical meetings.
- Perform other duties as assigned.
- PhD degree in physics, electrical engineering, materials science, or a related field.
- Significant experience in the design and operation of optical and optoelectronic instrumentation.
- Ability to write and operate software (e.g., Python, MATLAB, LabView) for hardware control, data collection, and data analysis of experimental systems.
- Strong fundamental knowledge of solid-state physics and the principles underlying light-emitting semiconductors
- Ability to perform as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution, including developing innovative solutions to scientific and technical problems. - Experience developing independent research projects, including publication of peer-reviewed literature.
- Proficient verbal and written communication and interpersonal skills to collaborate effectively in a multidisciplinary team environment and present and explain technical information.
- Effective initiative and interpersonal skills and ability to work in a collaborative, multidisciplinary team environment.
- Significant working experience with and theoretical understanding of high-power semiconductor laser diode devices.
Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.
Security Clearance: This position requires a Department of Energy (DOE) Q-level clearance.
If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. Q-level clearance requires U.S. citizenship. If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted. For additional information, please see DOE Order 472.2 .
Note: This is a one year Postdoctoral appointment with the possibility of extension to a maximum of three years. Eligible candidates are those who have been awarded a PhD at time of hire date.
