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.

Workshops at LLE

Magnetic Fields in Laser Plasmas Workshop

The Magnetic Fields in Laser Plasmas Workshop was held 23–24 April at LLE as a satellite meeting to the Annual OMEGA Laser Users' Group meeting (OLUG). Presentations given at the workshop can be found here. The meeting served to bring together those working on laser experiments and simulations with imposed magnetic fields to discuss the state-of-the-art, outstanding physics issues, future directions, and collaborations at a time of expanding opportunities. There were 36 external attendees, from 21 different institutions in 6 different countries: the U.S. (29 attendees), Canada (1), the UK (1), Japan (2), France (2) and Spain (1), demonstrating the worldwide interest in this growing area of research.

From the Director

24 May 2018


To Staff, Students, and Colleagues:


The Senate approved their FY 2019 Energy and Water Development Appropriations Bill today.


I am pleased to report their mark was favorable to the Laboratory. All of your efforts and hard work at the Laboratory and in the overall National Program, are valuable and recognized.


The Bill includes $80 million for the Laboratory. This is the highest funding level ever proposed for LLE. My thanks go to our Congressional delegation (in particular, Senator Schumer), the University's Congressional Relations Team, and all of you for your hard work and dedication.


There is still work to e done for a final FY 2019 Bill but the language in the Senate mark sends a strong message to the Administration.


The budget language is below for your reference.

Thank you and best wishes,



Inertial Confinement Fusion Ignition and High-Yield.

The Committee finds that the Inertial Confinement Fusion and High Yield [ICF] program continues to be a critical and essential component of nuclear stockpile certification without underground nuclear weapons testing, maintaining U.S. leadership in high energy density physics and laser technologies, and developing the next-generation workforce. Therefore, the Committee recommends $544,934,000 for the ICF program. Within available funds, the Committee recommends $344,000,000 for inertial confinement fusion activities at the National Ignition Facility, $63,100,000 is recommended for Sandia National Laboratory's Z facility, and $80,000,000 is recommended for the University of Rochester's Omega facility. Within available funds for facility operations and other amounts, the Committee recommends not less than $30,000,000 for target research, development, and production. To ensure a robust, diverse, and competitive vendor base for targets, the Committee directs the NNSA to compete as much scope as practicable and limit sole-source contracts to $15,000,000 or less. The Committee further encourages continued research by the NNSA in High Energy Density Plasmas and recognizes the partnerships between the laboratories and research universities to address the critical need for skilled graduates to replace an aging workforce at our NNSA laboratories.
