Compact Hybrid Laser System for Threat Neutralization [in Milliseconds (not Seconds) with 100 kW Average Power and 100 GW Peak Power]

High-energy laser (HEL) architectures utilized in directed energy weapon (DEW) platforms rely upon high average power outputs and relatively slow (thermal) damage mechanisms, requiring 15+ second engagement times in practical situations. Engagements of this nature do not properly address the evolving set of asymmetric threats, specifically hypersonic and sUAS systems. This proposal presents a new paradigm of laser engagement, leveraging rapid high intensity damage mechanisms and reducing system SWaP without sacrificing average power deposition. Combining rapid material removal with current HEL engagement will lead to order-of-magnitude reductions in threat engagement timescales. Solid-state lasers (SSLs) constitute a vital aspect of the DoD’s directed energy engagement strategy, including the HELSI program aimed at HELs surpassing 500 kW in the near future. High-average, high-peak power outputs are directly attainable from such architectures. Development of the proposed system will be based on the transitional development of current commercial Burst-Mode Solid-State Lasers available at Spectral Energies, leading to practical, multi-platform realizations on the battlefield.
