The U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) awarded a $499,999 Project Grant to Fuceltech Inc. DBA Princeton Innotech under ARPA-E FOA Number DE-FOA-0003164 (SPARKS) on December 31, 2024. The purpose of this grant is to address the development of the next generation of diode pump lasers for inertial confinement fusion (ICF) applications at Lawrence Livermore National Laboratory (LLNL). The key objectives are to increase the pump power density of the diode lasers from the current state-of-the-art of 8 kW/cm2 to 11 kW/cm2, with a reach goal of 20 kW/cm2. This research and development project aims to advance the state-of-the-art in diode pump laser technology to support the increasing pulse energy requirements for LLNL's ICF program, which utilizes a combined 4 MJ pulse energy from 192 beamlines. The grant has a period of performance from December 31, 2024 to March 1, 2026.
