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.

High School Students Present at the Omega Laser Facility Users Group Workshop

The Fifth Omega Laser Facility Users Group Workshop was held 24–26 April 2013. This year, presentations included posters given by three participants in LLE's 2012 Summer High School Research Program. Emily Armstrong (left), who attends Our Lady of Mercy High School, was a semifinalist in the 2013 Intel Science Talent Search competition. Christa Caggiano (center) attends Victor Senior High School, and Raz Rivlis (right) attends Brighton High School. A more detailed description of their projects is available here. This summer the Summer High School Research Program will begin its 25th year on 8 July 2013.

Multi-FM SSD Beam Smoothing
on OMEGA EP

The Laboratory for Laser Energetics (LLE) has developed the polar-drive (PD) concept to enable direct-drive–ignition experiments to be conducted while the National Ignition Facility (NIF) is configured for indirect-drive ignition. This concept has been part of the research program at LLE since the inception of the National Ignition Campaign in 2005. With the goal of designing a cryogenic PD ignition platform compatible with existing NIF laser specifications, LLE has created, tested, and deployed a system of smoothing by spectral dispersion (SSD) using multiple-frequency modulations in a single dimension (Multi-FM 1-D) on OMEGA EP.
