High Energy Laser Research Initiatives

The High Energy Laser Research Initiatives program, managed by the Office of the Secretary of Defense, is a basic research effort executed through the Joint Directed Energy Transition Office (JDETO). Its primary goal is to support the Department of Defense's (DoD) long-term strategy for directed energy technologies, as outlined in the DoD Directed Energy Roadmap. The program is designed to build a sustainable advantage in directed energy capabilities, foster a resilient joint force, and strengthen the defense innovation ecosystem.

The program funds foundational research in high energy laser (HEL) and high power microwave (HPM) technologies. These efforts are intended to generate the scientific knowledge necessary to underpin future DoD directed energy weapon systems. Such systems offer operational advantages, including speed-of-light engagement, high precision, low incremental cost per use, and reduced logistical burdens compared to traditional munitions. The research aims to address scientific and technical challenges that currently limit the scalability, efficiency, and operational utility of HEL and HPM systems.

A key component of this program focuses on improving the fundamental understanding and modeling of HEL and HPM sources, devices, and beam control technologies. Research activities include atmospheric characterization, metrology, control systems, algorithms, waveguides, antennas, and beam control components. The program also monitors and leverages national and international advancements in laser and microwave technologies, aiming to incorporate innovative developments that could enhance power scalability and system performance.

In FY 2025, research will continue into new laser and microwave technologies with potential for scalability and military application. The program will also explore advanced beam control methods and architectures that could improve the performance of directed energy systems. These efforts are coordinated with the DoD Directed Energy and Non-Lethal Weapons Science and Technology Community of Interest to ensure harmonization and avoid duplication across the department.

In FY 2026, following a realignment of funding from foundational research, the program will focus on the Directed Energy Center of Excellence. This technical program within JDETO supports workforce development and international collaboration. The workforce development initiative seeks to cultivate the next generation of scientists and engineers specializing in directed energy by partnering with universities and conducting studies to assess long-term workforce needs. The program also establishes a Joint Directed Energy Consortium to foster a collaborative research community and award new university research efforts.

International collaboration is another objective of the Center of Excellence Program. The program works with organizations such as the European and Asia Offices of Aerospace R&D within the Air Force Office of Scientific Research to fund university grants. These grants emphasize partnerships between U.S. and international universities, promoting foundational research in directed energy and leveraging global expertise to advance the field.
