Welcome to LLE

The Laboratory for Laser Energetics (LLE) of the University of Rochester is a unique national resource for research and education in science and technology. LLE was established in 1970 as a center for the investigation of the interaction of intense radiation with matter. The National Nuclear Security Administration funds LLE as part of its Stockpile Stewardship Program.

Gas-Bag Target

As part of the National Laser Users' Facility program, The Massachusetts Institute of Technology (MIT), Luxel Corp., and General Atomics designed and built a new gas-bag platform to study fundamental astrophysical phenomena, including the propagation, interaction, and instability of astrophysical jets and plasma shocks. The resulting data will provide insights into and advancement of fundamental issues surrounding frontier astrophysics and basic high-energy-density physics. The goal of MIT's experiments at LLE will be to generate a magnetized collisionless shock by driving a supersonic plasma flow into the pressurized gas-bag in the presence of external magnetic fields.

From the Director

Senator Schumer Visits to Show Support for LLE

14 March 2018


To Staff, Students, and Colleagues:


Thank you for the support all of you have given to LLE. It is difficult to imagine that after five decades of contributions to the ICF and high-energy-density programs, committed service to the National Laser Users' Facility community, and more than 500 graduate students later from the University of Rochester and other great universities, that the Laboratory has been targeted for complete shutdown. The President's budget is forcing the Department of Energy to close the Laboratory by 2021.


For years OMEGA and OMEGA-EP have provided wonderful research opportunities for our community. For years we have all done it successfully. If this research is to continue, we must all come together as a community and ask Congress to re-establish full funding for LLE and for the Inertial Confinement Fusion Program so we can support this research for years to come. Please consider signing the petition at Change.org.


Again, my thanks to ALL of you for supporting the entire national program and the Laboratory for Laser Energetics.



Mike Campbell
