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.

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 Grism Stretchers to Manipulate Temporal Profiles

Senior Laboratory Engineer, Sara Bucht, is shown here with the grism stretcher that she designed and built, which uses gratings mounted next to prisms to form "grisms." The grism stretcher is used to manipulate the temporal profile of OPAL (optical parametric amplifier line) in order to compress the typically discarded idler pulse. To stretch the pulse to almost a nanosecond pulse duration, large custom optics are used, which resulted in a daunting design process requiring navigation through a parameter space involving 11 total variables. The inset shows the prism with the grating.

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.
