Berkeley Lab's Chemical Sciences Division has an opening for a Experimental Ultrafast Molecular Science Postdoctoral Scholar. The Atomic, Molecular and Optical Sciences (AMOS) research group at Berkeley Lab (LBNL) seeks to answer fundamental questions in atomic, molecular and chemical sciences by employing existing and currently emerging tools such as synchrotron radiation, lasers, laboratory-based extreme ultraviolet sources, and electron beams. The incumbent will combine these with state-of-the-art theory and experimental techniques including charged particle momentum imaging, electron-ion coincidence, extreme ultraviolet and x-ray nonlinear spectroscopy, scattering, and transient absorption, we investigate fundamental chemistry and physics over a broad range of time scales and systems.
The LBNL AMOS group seek a Experimental Ultrafast Molecular Science Postdoctoral Scholar experienced in the design and operation of ultrafast laser systems and molecular physics experiments to join our team investigating fundamental electronic and chemical dynamics of unimolecular and few-molecule reactions on their ultrafast timescales. The work will be performed in laboratories dedicated to high pulse energy few-femtosecond Ti:sapphire lasers and an established high-order harmonics generation (HHG) beamline generating tabletop vacuum ultraviolet and extreme ultraviolet photons. The techniques will include spectral selection and analysis of tabletop infrared/visible/ultraviolet photons, polarization-sensitive probe schemes for nonlinear extreme ultraviolet optical spectroscopy, and photoionization electron and ion particle imaging.
What You Will Do:
Develop and perform experiments to investigate femtosecond time-resolved physical and chemical and processes in various fundamental systems using ultrafast near infrared, visible and HHG tabletop extreme ultraviolet laser pulses.
Develop nonlinear optical spectroscopy techniques, such as Optical Kerr Effect and stimulated Raman spectroscopy to access detailed information on transient atomic and molecular species.
Use frequency domain techniques, such as lock-in amplification, to extract small photon signals with high sensitivity.
Develop optical and charged particle spectroscopy techniques, such as photoelectron spectroscopy, ion time-of-flight and transient absorption spectroscopy to access detailed information on transient atomic and molecular species using ionizing and non-ionizing probe pulses.
Publication of the research results in peer-reviewed journals and international conferences.
What Is Required:
PhD in physics or physical chemistry and experimental experience with ultrafast laser techniques or XUV/soft x- ray spectroscopy.
Demonstrated experience with high pulse energy ultrafast laser design and operation, chirped pulse amplification, pulse shaping and compression, and optical parametric amplification.
Demonstrated expertise in high-order harmonics generation or tabletop vacuum and extreme ultraviolet pulse generation.
Demonstrated expertise in nonlinear optical spectroscopies and related techniques.
Experience with noisy signal detection and processing using phase-sensitive detection techniques.
Experience with fast data acquisition and computer programming (e.g. Python, C++, Labview).
Experience with collection, analysis and interpretation of multidimensional experimental data sets.
Experience with electronics and mechanical technologies for ultrafast lasers and photoelectron spectroscopy, including fast photon and particle detectors (e.g. avalanche photodiodes, microchannel plates), fast amplifiers, analog-to-digital conversion, motion control and imaging for optical systems, and ultrahigh vacuum systems.
Additional Desired Qualifications:
Experience with particle imaging techniques such as velocity map imaging and electron-ion coincidence momentum imaging spectroscopy to access detailed information on atomic and molecular products following dissociative photoexcitation and photoionization.
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. You must have less than 4 years paid postdoctoral experience. 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.
Work will be primarily performed at: Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.

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.
