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.
