The BELLA Center and ATAP division conduct laser research and laser-driven plasma accelerator research. Laser techniques include fiber laser experiments to develop spatiotemporal pulse combination systems, high energy fiber amplifiers, and electronic stabilization methods. They also include Ti:sapphire lasers, some with temporal broadening to access the few-cycle regime, and their use to drive laser-plasma accelerators.
In this role, your primary research responsibility will be to perform experimental research to develop and apply high repetition rate, terawatt, ultrafast laser technology including temporal and spatial pulse combination, nonlinear broadening and compression, advanced digital control concepts, and precision control of output pulse characteristics. You will participate in laser applications work focused on driving laser-plasma acceleration.
What You Will Do:
Characterize different kinds of fiber amplifiers in temporal and spectral regimes, and use data to refine numerical models for system design and optimization.
Build and perform experiments to investigate coherent pulse combination schemes, comparing different stabilization algorithms and sensing methods.
Build and test optical systems to broaden and compress energetic ultrashort laser pulses using fibers and gas media to the few-cycle regime.
Apply generated laser pulses to laser-plasma acceleration.
Model and simulate nonlinear pulse dynamics using self-developed codes and commercial software.
Document and communicate the results of work in reports and oral presentations, including participation in meetings, reviews, conferences and publications in refereed journals.
What is Required:
Ph.D. in Physics or Engineering, in the laser or optics field.
Experimental experience with coherently combined ultrafast fiber laser systems, their diagnostics and controls, and/or the operation and characterization of ultrashort-pulse CPA lasers.
Experience in simulations or modeling of ultrafast laser phenomena.
Ability to work closely in a team with other scientists, postdocs, graduate students and technicians.
Ability to optimize experimental design, analyze data, and compare with numerical models using commercial or in-house developed software.
Excellent verbal and written communication skills.
Additional Desired Qualifications:
Experience with laser-plasma interactions and acceleration.
Experience with laser beam shaping and beam stabilization.
Familiarity with mechanical engineering principles of optomechanics.
Experience with programming (Labview, Matlab, Python, C++, etc.) and optical design software (Zemax, etc.).
The posting shall remain open until the position is filled.
This is a full time, 1 year, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. Salary for Postdoctoral positions depends on years of experience post-degree.
Full-time, M-F, exempt (monthly paid) from overtime pay.
This position is represented by a union for collective bargaining purposes.
Salary will be predetermined based on postdoctoral step rates.
This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
