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.

LLE High School Program Feedback

Shown is a photo from 2003 of LLE senior scientist Reuben Epstein and his then high school student Wen-fai Fong. After graduating from Pittsford Sutherland High School, Wen-fai double majored in physics and biology at MIT and then moved to Harvard for her Ph.D., where she established a mentoring program for graduate students. Wen-fai's Ph.D. thesis was recently named the 2016 Outstanding Doctoral Thesis in Astrophysics by the American Physical Society. She is currently at the University of Arizona's Steward Observatory on an Einstein Postdoctoral Fellowship. Following the award, she wrote her advisor, "I truly appreciate the time you spent with me early on in my career. I think my early experiences in physics and astronomy with kind and patient mentors such as yourself were crucial in solidifying my career aspirations to continue in this field permanently. . . . it was really a very formative summer for me. You are changing lives through the program!" Applications for the 2017 Summer High School Program are now available.

Around the Lab

Laser and Target Area System Developed for the Dynamic Compression Sector

The University of Rochester's Laboratory for Laser Energetics (LLE) developed a 100-J UV laser and target area system for the Dynamic Compression Sector (DCS) at the Advanced Photon Source (APS) located at the Argonne National Laboratory near Chicago. This new research facility is operated by Washington State University (WSU) under sponsorship from the National Nuclear Security Administration (NNSA). LLE partnered with Logos Technologies to develop and build the high-energy laser, which is suitable for a broad range of applications. The APS is a state-of-the-art user facility dedicated to dynamic compression science, a field that researches materials under extreme conditions.
