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.

Use of a Test Bench to Verify the TOP9 Relay Lens

The tunable OMEGA P9 beam (TOP9) is being used to develop a CBET platform and explore multicolor cross-beam energy transfer (CBET) mitigation strategies using a wavelength tunable (1‑nm), 351‑nm UV beam at the Omega Laser Facility. As part of the large infrastructure needed to propagate that beam, a custom long-radius test bench was designed to determine the focal length of the TOP9 relay lens. Shown is Senior Laboratory Engineer, Sam Agnello, working on the system.

From the Director

12 September 2018


To Staff, Students, and Colleagues:


We have wonderful news!! Josh Farrelman from the Office of Government and Community Relations sent the following email to me on Monday:


"I am very pleased to report that the final FY 2019 Energy and Water bill that was just released and Congress is set to approve as early as this week will provide $80 million for the LLE and $545 million for the Inertial Confinement Fusion program at the National Nuclear Security Administration.


As you may recall, the President had proposed $45M for the LLE and $418M for the ICF program and closing LLE in 3 years. This was further hampered by the death of Louise and indictment of Rep. Collins. However, thanks to incredibly strong, bipartisan Congressional support led by Sen. Schumer and an outcry from the scientific community, we not only reversed a $30M cut and proposed closure of the LLE, but we secured a $5M increase over last year. This represents an unprecedented $12M increase over the last two fiscal years. The $80M represents the highest level of federal funding ever appropriated to the LLE in the University's history and will serve as a critical basis for the first year of our new Cooperative Agreement with the DOE."


Thank you, ALL of you, for your great work, dedication, and advocacy with all stakeholders. Your support, and that of Congress, has been tremendous!!

Thank you and best wishes,
