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.

A New Prototype Stage for Glancing Angle Deposition Coatings Research

Optical Manufacturing Process Engineer, John Spaulding, and Coating Operator, Justin Foster, are shown installing an optic on a new prototype stage built to support research and development work on glancing angle deposition (GLAD) coatings. The deposition system is designed to allow for growth of an oriented, birefringent film structure in stripes across an optical surface, and the resulting film thickness is controlled such that each stripe region is a quarter-wave plate. This custom stage, designed and built by Angstrom Engineering, has movements for x and y translation, tilt, and rotation that make it possible to manipulate the part during deposition in order to control the resulting film structure, and the stage will be able to coat up to a 100-mm-diam optic. GLAD coating research supports the potential manufacture of a distributed polarization rotator (DPR) component that would be integral to beam-smoothing efforts for direct-drive or polar-direct-drive campaigns at the National Ignition Facility.

Custom-Printed Circuit Board Development by LLE's Electronics and Controls Engineering Group

The 24 engineers and technicians who form the Electronics and Controls Engineering Group at the University of Rochester's Laboratory for Laser Energetics have procured new equipment to efficiently construct custom-printed circuit boards (PCB's). Custom PCB prototypes, which are applied to laser-fusion research, can be designed, assembled, documented, tested, and corrected in-house in just a matter of days.

Here, Senior Manufacturing Engineer Joe Romano is shown using an automated Manncorp 7722FV pick-and-place machine to assemble PCB's for the solid-state Pockels-cell driver.
