Programmable Time-Varying Spectral Encoding for Advanced Control of High-Energy, High-Power Laser Systems

Executive Summary

We are developing a novel capability to pattern the amplitude and wavelength of laser pulses at picosecond timescales. This research will expand the capabilities of high-energy, high-power laser systems, providing new tools to optimize laser-matter interactions and achieve breakthroughs in inertial confinement fusion, high-energy-density science, directed energy, and advanced manufacturing in support of national missions.
