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.

Sharon Weiss

Sharon Weiss is Director of Vanderbilt Institute of Nanoscale Science and Engineering, a multidisciplinary institute that supports research, education, and K–12 outreach across science, engineering, and medicine. A native of Rochester, NY, Prof. Weiss received B.S. (1999), M.S. (2001) and Ph.D. (2006) degrees from the Institute of Optics at the University of Rochester. Weiss' Ph.D. thesis was supervised by Prof. Philippe M Fauchet. She received a National Defense Science and Engineering Graduate Fellowship from the Office of Navy Research and a Robert L. Sproull Fellowship from the University of Rochester to support her graduate research. Her research also benefitted from use of the LLE laboratories and collaboration with the LLE scientific staff including Ken Marshall and Prof. Stephen Jacobs.

New NASA Black Hole Visualization
Created by LLE Alum

Using custom software at the Goddard Space Flight Center, NASA research astrophysicist Jeremy Schnittman created a visualization of a black hole that illustrates how gravity distorts our view. Jeremy’s first experience with scientific computer modeling was as an LLE summer high school intern when, under the supervision of Stephen Craxton, he developed a code to calculate the uniformity of x-ray heating in hohlraums. Jeremy continued his research during the following summers while attending Harvard University, publishing his first scientific papers and contributing to a series of tetrahedral hohlraum experiments on OMEGA that he had proposed. His current research interests include: modeling x-ray spectra from black-hole accretion flows, black-hole binaries, gravitational wave sources, electromagnetic counterparts to binary black-hole mergers, dark matter annihilation around black holes, resonant dynamics of planetary systems and analogs, and modeling exoplanet atmospheres.

OMEGA Laser System Second
Line-of-Sight Project

Achieving controlled thermonuclear fusion, an energy source with the potential to provide a virtually unlimited source of clean energy, requires diagnostics to better understand the complex process that takes place in inertial confinement fusion (ICF) experiments. Due to the 3-D nature of these experiments, measurements are needed over multiple orthogonal lines of sight to maximize the coverage required to infer 3-D performance metrics.
