NEW COMPETITIVE COOPERATIVE AGREEMENT WITH POLYMATH RESEARCH INC. UNDER FOA NUMBER DE-FOA-00002459 (OPEN 2021) AND CONTROL NUMBER: 2459-4421 PROJECT TITLE: LONGER WAVELENGTH LASERS FOR INERTIAL FUSION ENERGY WITH LASER-PLASMA INSTABILITY CONTROL: MACHINE LEARNING OPTIMUM SPIKE TRAINS OF UNEVEN DURATION AND DELAY (STUD PULSES). IN THIS PROJECT, WE WILL CONDUCT LABORATORY EXPERIMENTS TO SHOW HOW DIFFERENT PARAMETRIC INSTABILITIES IN HIGH ENERGY DENSITY PLASMAS CAN BE CONTROLLED USING STUD PULSES FOR IFE APPLICATIONS. WE WILL TREAT THIS TASK AS AN INVERSE PROBLEM AND AN OPTIMIZATION SEARCH.
