Ultrafast Nonlinear Spectroscopy Postdoc – | Lawrence Berkeley National Laboratory

Ultrafast Nonlinear Spectroscopy Postdoc – 94208

Organization: CH-Chemical Sciences

Lawrence Berkeley National Lab’s (LBNL, https://www.lbl.gov/) Atomic, Molecular and Optical Sciences (AMOS) group of the Chemical Sciences Division (https://chemistry.lbl.gov/) is seeking a Postdoctoral Researcher to join our team to investigate the electronic and nuclear dynamics of molecules in excited electronic states by extreme ultraviolet nonlinear spectroscopy. 

The AMOS group seeks to answer fundamental questions in atomic, molecular, and chemical sciences by employing existing and currently emerging tools such as free electron lasers, laboratory-based extreme ultraviolet sources, synchrotrons, electron beams, coupled with advanced electron, ion, and photon detection techniques. Combining these with state-of-the-art theory, we investigate fundamental chemistry and physics over a broad range of time scales and systems. 

The successful postdoctoral fellow is experienced in the field of experimental ultrafast science, specifically Ti:sapphire lasers with multiple stages of amplification including regenerative and multipass amplifiers, an ultrahigh vacuum beamline with remote-controlled in-vacuum optical components, and ultrafast transient nonlinear spectroscopy methods. 

What You Will Do:

  • Conduct research on time resolved electronic and structural dynamics of excited molecules in gas and condensed phases using femtosecond extreme ultraviolet light pulses, exploiting probes of molecules such as nonlinear optical phenomena.  
  • Be responsible for the day-to-day safe operation of a tabletop high harmonics light source and nonlinear spectroscopy experiments in a dedicated laser laboratory.  
  • Develop and maintain state-of-the-art instrumentation, such as hardware and software for data acquisition and analysis, laser oscillator, amplifier and beamline alignment, and periodic maintenance and cleaning optical components. 
  • Participate in larger ongoing highly-collaborative projects, which target the investigation of molecular dynamics and electron correlation effects, using synchrotron radiation at the Advanced Light Source at Berkeley Lab and the X-ray free electron laser at the Linear Coherent Light Source II.  
  • Prepare high-quality manuscripts reporting your research for publication in peer-reviewed journals. 
  • Employ excellent communication skills to present your research at international conferences.   
  • Contribute to our high safety standards, data records, documentation, and infrastructure that enable the high standard of research across the group. 
  • Provide research support, assistance and instruction to other members of the work group as requested.  

What is Required:

  • Ph.D. in Experimental Physics, Chemistry, or a related discipline.
  • Demonstrated ability to collect, analyze, and document experimental research.
  • Demonstrated experience with the operation of ultrafast laser systems, tabletop optical systems, and instrumentation control systems.  
  • Expertise in ultrafast photon spectroscopy and detection methods. 
  • Experience in the operation of photon, ion or electron detectors (e.g. multi-channel plates, high-speed/high-sensitivity cameras), data acquisition and on-the-fly analysis (using e.g. Labview, Matlab, Python). 
  • Experience in analysis of multidimensional data sets and/or simulation of experiments.  
  • Experience with routine troubleshooting and maintenance of ultrafast Ti:sapphire laser systems employing chirped pulse amplification, pulse shaping and compression, and high harmonic generation.  
  • Communicate results in group meetings and participate in professional activities.  

Desired Qualifications:

  • Skilled in the instruction and training of students and junior researchers.
  • Excellent communication for the preparation of research publications (both oral and written) reporting the results of your research.
  • Demonstrated ability to work effectively with others in a collaborative research environment.  
  • Track record of innovative design, fabrication, and/or assembly of ultrafast laser apparatus, optical, electronic, or mechanical components.
  • Demonstrated ability to convey technical information through well-written and concise documentation.  

This position will remain open until filled. 

Notes:

  • This is a full-time, one 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 four years of paid postdoctoral experience. 
  • Salary for Postdoctoral positions depends on years of experience post-degree.
  • 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.
