State-of-the-art high-intensity laser facility at the University of Nebraska-Lincoln (UNL) dedicated to the experimental science, technology, and applications of extreme light.
Infrastructure: Located on three floors of the Behlen Lab building on the UNL city campus. Laboratories meet stringent requirements on temperature (±1 C), humidity (5%), and vibration control, made possible by separate designated electrical, processed-chilled-water, and air-handling systems.
High-power lasers: Three separate and independent laser systems: (1) Peak power from 0.2 - 0.7-PW at 0.1-Hz repetition rate, (2) Peak power 100-TW at 10-Hz (3) Peak power 10-TW at 10-Hz. Ti: sapphire chirped-pulse amplification lasers are operating at 800-nm in 30-fs duration pulses.
Laser diagnostics: Real-time measurement and optimization at full power of pulse characteristics on target: energy, contrast and spatial mode.
Target rooms: Three each. Two are radiation-shielded for radiological safety.
Target chambers: High-vacuum, sized 72”x48”x24”. Motor-driven and remotely-operable optical mounts.
Beamlines: Independent pulse compression systems allow for independent control of pulse durations of dual and separate beams used in the same experiment. Wavefront sensors and deformable mirrors control spatial phase. Spatial and temporal active feedback control provides consistent transform-limited pulses and diffraction-limited focusing on interaction. High numerical aperture focusing optics allow highly relativistic intensities to be achieved with laser light of either or both the fundamental frequency (800 nm) or its second harmonic (400 nm).
Electron accelerator: Synchronized laser-wakefield-driven, quasi-monogenetic 100-400 MeV electron beams. [Note: Due to the complexity of this capability, it is provided by the facility only for collaborative experiments.]
X-ray light source: Synchronized x-rays (10 keV – 10 MeV) from bremsstrahlung, K-alpha, betatron, or Compton scattering. [Note: Due to the complexity of this capability, it is provided by the facility only for collaborative experiments.]
Control rooms: Remote monitoring and control of laser and experimental parameters.
Permanent staff: 3 senior scientists, 2 technicians, 1 lab manager, 1 administrative coordinator assist users with safe and effective experimental campaigns. A trained laser-safety officer responsible for safety training and accountability. State-licensed accelerator facility, with radiation-safety monitoring and training.
In-house laboratory services: Operational procedures comply with EAR and ITAR export control regulations. In-house machine and electrical shops.
Visitor amenities: Ample office space. Downtown Lincoln city-campus location offers a wide variety of housing, restaurants, and entertainment walking distance from the laboratory.

LaserNetIn an effort to enhance access to similar facilities with femtosecond-to-picosecond laser capability, the Department of Energy’s Office of Fusion Energy Sciences recently established LaserNetUS, a consortium of laser facilities at universities and laboratories. These facilities will host user experiments (see list here). ELL will participate in LaserNetUS: a fraction of 2019 shot time on the Diocles and Archimedes platforms will be reserved for LaserNetUS. Potential ELL users are encouraged to apply to LaserNetUS when the call for proposals for LaserNetUS is issued.
Special RequirementsIf your proposal is funded for the ELL facility, please send us a pdf of the proposal alongside a description of your additional experimental requirements that will help ELL designate the correct personnel, laser, and equipment needs for your experiment. Please upload all forms below.
