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.

From the Director


21 February 2018


To all LLE and our colleagues in the community:


Yesterday I, along with members of our A++ Washington team, met with key staff of Congresswoman Louise Slaughter, Congressman Tom Reed, Congressman Chris Collins, and Senator Chuck Schumer.  Congress is in recess so we were very pleased that they would see us when they traditionally “take off” during this time.


There was widespread, bipartisan and enthusiastic support of LLE and the ICF Program overall. In all of our discussions we spoke of the importance of the program and the role that LLE, our partner laboratories (LLNL, LANL, SNL, NRL) target contractors, and colleagues in Universities play in making it the world's best effort in inertial confinement fusion, high-energy-density science, and laser science and technology.

They were shocked and upset with the President’s FY2019 budget (PBR) and out-year plans and all said they would work together to reverse them. They also reminded us that the PBR is a first step and request but they have the power of the purse.

Today's @Rochester published a statement from Interim President Designate Feldman which is pasted in my message below.


Please stay tuned to this page for future updates.






Statement from Interim President Designate Richard Feldman on LLE and President Trump's FY19 Budget Request


February 20, 2018
The University was disappointed to learn that the Administration’s fiscal year 2019 budget proposes a significant cut to the Laboratory for Laser Energetics (LLE) in FY19 and “a three-year ramp-down” in federal support. We are trying to make sense of this proposal, which jeopardizes the cutting-edge science and world-class education being conducted at the Lab.

The Lab is exceeding all its scientific milestones set by the U.S. Department of Energy and has grown to be DOE’s largest university-based research center in the nation. It is home to the DOE’s National Laser Users’ Facility, which brings more than 400 scientists from across the country and the world to Rochester to use its facility, and is in the final stages of its renewal of its 5-year, $345M Cooperative Agreement with the federal government. In addition to the more than 350 highly skilled scientific and engineering staff, over 100 students from multiple institutions are conducting research on LLE’s state of the art laser facilities.

Although we are concerned by these developments, we are encouraged by the historic, strong bipartisan support the LLE has enjoyed from the New York Congressional delegation, the State of New York, and the U.S. Congress, which recognizes the significant contributions the LLE makes to national and economic security, as well as the strategic work being done that can lead to an independent energy future.

We thank and acknowledge our Congressional delegation for their consistent leadership and support. We are also heartened by the recent two-year bipartisan budget agreement agreed to by Congress that provides increased funding for university-based scientific research. We look forward to working with our delegation to provide robust, sustainable support for the LLE in FY18 and FY19 and avert this potentially devastating cut so it can maintain U.S. global leadership and security and continue to be an engine for regional economic growth and innovation.

NY Times Article Features Experiment
at the Omega Laser Facility

On 5 February, the New York Times Science section posted an article that features an experiment that was conducted at the Omega Laser Facility under the LLE Laboratory Basic Science Program and was recently published in the journal Nature Physics. The paper discusses a new "strange" form of water that is simultaneously solid and liquid. The paper highlights experiments conducted by a team comprised of scientists from Lawrence Livermore National Laboratory (LLNL), the University of California Berkeley, and the University of Rochester and led by Marius Millot, a physicist at LLNL. This new form of water is called "superionic water" and is not known to exist naturally on Earth. Scientists created it by squeezing water between two pieces of diamond to create a type of ice that is about 60% denser than usual. Then, on the OMEGA Laser System, a pulse of laser light was used to heat the ice to thousands of degrees to exert a pressure more than a million times that of Earth's atmosphere. These conditions exist inside Uranus and Neptune and undoubtedly within numerous ice giants around other stars. A solicitation for proposals for the FY19 Laboratory Basic Science Program is currently underway.
