Lawrence Berkeley National Lab’s (LBNL) Accelerator Tech-Applied Physics (
ATAP) Division has an opening for a Physicist Postdoctoral Fellow to join
the team.

In this exciting role, you will work on developing ultrafast fiber laser
technologies and their novel applications on laser-plasma accelerators (LPA)
. The BELLA Center at LBNL’s ATAP Division seeks to develop high repetition
rate, terawatt, ultrafast fiber laser technology, with the goal to drive
multi-kHz, MeV-class LPAs.

You will explore novel methods in the field, including coherent combination
of laser pulses in temporal, spectral, and spatial domains, gain narrowing
compensation, state-of-the-art high-power fiber amplification, nonlinear
pulse compression, new LPA methods, and advanced digital control of laser
and accelerator systems including machine learning. Combining these methods
with numerical and analytic physics models, we have been running proof-of-
principle demonstrations of energy-scalable technologies, moving toward
increasingly energetic laser systems.

What You Will Do:
Design and perform experiments to investigate the spectral combination of
fiber chirped-pulse amplifiers (FCPA), as well as temporal stacking of
amplified femtosecond pulses using cascaded optical interferometers.
Investigate pulse dynamics (including nonlinearity, gain narrowing and
saturation, dispersion) in multi-stage, high-power FCPA systems, their
interplay with coherent combination processes for amplified pulses, and
methods to control and optimize them.
Characterize different kinds/designs of large-mode-area fiber amplifiers in
temporal and spectral regimes, and use data to refine numerical models for
system design and optimization.
Study and apply feedback control methods to stabilize the temporal and
spectral combination of amplified, ultrashort laser pulses. Explore advanced
digital control concepts, including machine learning, for laser and
accelerator systems.
Document and communicate the results of work in reports and oral
presentations, including participation in meetings, reviews, conferences,
and publications in refereed journals.

Additional Responsibilities as needed:
Build and test optical systems (fiber and free-space) to spectrally broaden
and temporally compress energetic ultrashort laser pulses to the few-cycle
regime, by manipulating optical nonlinearity and dispersion.
Study and conduct low-energy (kHz, MeV) LPA experiments.
Build and perform experiments to investigate spatial beam combination
schemes, comparing different stabilization algorithms and sensing methods.

What is Required:
Ph.D. in Physics or Engineering, in the field of lasers, optics, or laser
applications.
Experimental experience with coherently combined ultrafast fiber laser
systems, their diagnostics and controls, or/and the design, characterization
, operation of high-power FCPA lasers.
Experimental experience with digital or/and analog feedback control of
optical/physical systems.
Experience with simulations or modeling of ultrafast laser systems.
Ability to work closely in a team with other scientists, postdocs, graduate
students, and technicians.

Desired Qualifications:
Experimental experience with nonlinear ultrashort laser pulse compression.
Experimental experience with laser-plasma interactions and acceleration.
Experience with programming and machine learning.
Excellent verbal and written communication skills.

Notes:
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 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.
Diversity, equity, and inclusion are core values at Berkeley Lab. Our
excellence can only be fully realized by faculty, students, and staff who
share our commitment to these values. Successful candidates for our faculty
positions will demonstrate evidence of a commitment to advancing equity and
inclusion.
Work will be primarily performed at Lawrence Berkeley National Lab, 1
Cyclotron Road, Berkeley, CA.

Equal Employment Opportunity: Berkeley Lab is an Equal Opportunity/
Affirmative Action Employer. All qualified applicants will receive
consideration for employment without regard to race, color, religion, sex,
sexual orientation, gender identity, national origin, disability, age, or
protected veteran status. Berkeley Lab is in compliance with the Pay
Transparency Nondiscrimination Provision under 41 CFR 60-1.4. Click here to
