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.

Focal-Spot Testing of an OMEGA
Distributed Phase Plate

An equivalent-target-plane diagnostic is shown being used to evaluate a new distributed phase plate (DPP) for the OMEGA Laser System. The diagnostic is situated on the same optical table that is used for ultraviolet holographic recording. An off-axis parabola (OAP) is used to expand a laser beam to the required clear aperture, while a second OAP and a series of interchangable optics are used to form a magnified focal spot. An R80 DPP (left), is being characterized within this test facility by Charles Kellogg, a member of the Optical and Imaging Sciences group. The mirror in the background is used to direct the expanded beam through the test optic.
