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.

Glancing-Angle Deposition for Distributed Polarization Rotators

The 40-in. coating chamber in the Optical Manufacturing (OMAN) group has been configured to produce coatings by glancing-angle deposition (GLAD). These electron-beam evaporated coatings condense on the surface of the substrate at a high angle of incidence, forming a birefringent film with an oriented columnar structure. By translating the substrate behind an aperture, the surface may be patterned with coated regions of quarter- and half-wave plates. Such a component enables spatially varying manipulation of incident polarization. Vern Gruschow and Jim Oliver of OMAN are shown with a 2-in test sample coated in the system along with the insert showing the film structure.
