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.

Alumni Snapshot

Maria Alejandra Barrios
Senior Data Scientist, In-Q-Tel

Dr. Barrios obtained her B.A. in Physics, Mathematics, and Philosophy from Gettysburg College and her Ph.D. in High-Energy-Density Physics and Plasma Physics from the University of Rochester in 2010. Her graduate thesis was titled: "Precision Equation of State Measurements on Hydrocarbons in the High Energy Density Regime" and her thesis supervisors were Profs. Thomas Boehly and David Meyerhofer. Dr. Barrios conducted her graduate research on the OMEGA Laser System at the Laboratory for Laser Energetics under a Frank J. Horton Fellowship.

In Memory of Andrey V. Okishev

Dr. Andrey Okishev passed away unexpectedly at age 59 on November 5, 2018. Dr. Okishev joined LLE in 1993 as a Research Associate and left as a Senior Scientist in 2014. During these 21 years, Andrey designed and built a number of unique and extraordinarily reliable lasers known as Omega master oscillators, diode-pumped regens, the damage-test laser and others. Dr. Okishev is the author of over 100 scientific papers. His contributions to the OMEGA and OMEGA EP lasers underpin the reliability and flexibility of these large-scale lasers.

Tens of lasers built by Andrey are still running in a number of systems in use at LLE. Among the scientists and laser engineers at LLE, these stand as a lasting memory and testament to the technical acumen of Dr. Andrey V. Okishev.

A Novel Statistical Model to Triple the Fusion Yield in Direct-Drive Laser Fusion

Accurate predictive capabilities are essential in the quest for thermonuclear ignition. In support of these predictive models, the Laboratory for Laser Energetics (LLE) has developed a novel statistical approach used to predict and design multiple cryogenic deuterium–tritium (DT) implosions on the OMEGA Laser System. This approach has led to the tripling of the fusion yield to its highest value for direct-drive laser fusion of DT-layered targets.
