2021 Annual Report

The Laboratory for Laser Energetics (LLE) is funded primarily by the U.S. Department of Energy (DOE) National Nuclear Security Administration’s (NNSA’s) Office of Experimental Sciences Inertial Confinement Fusion (ICF) Program through a fiveyear Cooperative Agreement. The fiscal year ending September 2021 (FY21) comprised the third year of LLE work under DOE/ NNSA Cooperative Agreement No. DE-NA0003856. The New York State Energy Research Development Authority (NYSERDA) and other federal agencies including the DOE Office of Science (Fusion Energy Sciences), Advanced Research Projects Agency– Energy (ARPA-E), and the National Science Foundation (NSF) also sponsor work at the Laboratory.

In all cases, high-quality science and technology advances were delivered while maximizing impact to our sponsors. This annual report summarizes work conducted at LLE during FY21 and includes research on the ICF and High-Energy-Density (HED) science campaigns; laser, optical materials and advanced technology development; operation of the Omega Laser Facility for the ICF and HED campaigns, the National Laser Users’ Facility (NLUF), the Laboratory Basic Science (LBS) Program, and other external users including the newly established LaserNetUS supported by the DOE Office of Fusion Energy Sciences (FES); and programs focusing on the education of high school, undergraduate, and graduate students. Most of this work has been submitted to and accepted by scientific journals and is also therefore covered in the 128 peer reviewed journal papers in 2021.
