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.

Wayne Knox

Wayne Knox's involvement with LLE began in 1976 when he began working with the LLE Glass Laser Development team as an RIT coop student. Later on, he transferred from RIT to the Institute of Optics and as an undergraduate laboratory assistant and became one of the founding members of Gerard Mourou's Ultrafast Science group at LLE. Wayne continued his graduate education at the Institute of Optics as an LLE fellow, doing his graduate research at the Laboratory and completing his Ph.D. in 1983. In 1984, he went to Bell Labs in Holmdel, NJ and worked as a Postdoctoral Fellow, was promoted to Member of Technical Staff in 1985, and to Distinguished Member of Technical Staff in 1990.

Ride, Run, or Walk with LLE in the Tour de Cure

Join LLE in the 2019 Tour de Cure, Saturday June 8 2019 in Webster, NY. The Tour is not just a cycling event; it has a 5K family fun walk, a 5K timed run, and cycling routes of 15, 25, 40, 62 and 100 miles. There is something for everyone, adults and children. Last year Team LLE had 25 cyclists, rode a combined 1100 miles, and raised an astounding $10,250. This year, the goal is to double the number of participants to 50. Every 19 seconds someone in the U.S. is diagnosed with diabetes, and 1 in 11 people will face this diagnosis in their lifetime. The money raised from the event goes to the American Diabetes Association, supporting their three pillars; Research, Education and Advocacy. To register for team LLE, visit: www.diabetes.org/teamlle

Using an Interferometer to Map Electron Density Gradients in HEDP Experiments

Pia Valdivia, Johns Hopkins University Research Scientist, is shown aligning the Talbot–Lau x-ray deflectometer for use in a National Laser Users' Facility experiment to benchmark the ten-inch manipulator (TIM)–based diagnostic on OMEGA EP (EP-TXD). The interferometer can map electron density gradients in high-energy-density physics experiments. The experiment aimed to characterize irradiated foils by mapping the ablation front for electron density values above critical density.

LLE Summer High School Student Contributes to High School Living Environment Curriculum

In a darkened room Katie Kopp shows her visitors examples of the complex molecular and cellular structures just beneath the surface of everything from paper towels to flower petals and human organs. The Victor High School senior is clearly excited about MUSE—the new microscope technology she used at LLE last summer. Kopp is helping make it possible for high school students to share her enthusiasm in their own classrooms.
