This Defense Intelligence Reference Document was prepared by the Defense Intelligence Agency's Defense Warning Office and dated 31 March 2010. It was produced under the Advanced Aerospace Weapon System Applications Program. It reviews chemical, solid-state, fiber, ultra-short pulse and free-electron lasers, as well as beam control, atmospheric propagation, DoD laser history and how spacecraft could be damaged by lasers. It projects that electrically powered lasers could enable MW-class weapons and spacecraft laser weapons within 20 years. It ends with shielding recommendations for spacecraft.
From the source: Release of 2026-09-18 Incident: 3/31/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys the development of high-energy laser weapons and notes that, although lasers had already become important military tools for ranging, guidance, and other lower-power uses, true weapon-class systems remained limited by power generation, beam control, atmospheric propagation, and logistics. The report reviews major laser types along with the optical, tracking, and thermal-management systems needed to make them militarily useful. It argues that high-energy lasers can offer important advantages over kinetic weapons in speed, precision, and low collateral damage, especially against softer or fast-moving targets, while also emphasizing that practical deployment has long been hindered by hazardous chemical fuels, thermal blooming in the atmosphere, power-supply constraints for mobile systems, and waste-heat removal.
UNCLASSIFIED/ f FO A OFFI€il.t.k YSE &P•tv State of the Art and Evolution of High-Energy Laser Weapons Summary The laser was invented in 1960, only 49 years ago, and (along with the light emitting diode) has evolved into an essential part of our modern every-day life in ways that cou ld not have been foreseen. On the military side, there have also been incredible advances in laser and beam control technolog ies but no deployment of any high-energy weapons. Many concepts have been developed and pursued, only to be discarded or deferred owing to technical immaturity, expected production cost, lack of apparent utility, or logistics concerns. The most significant technical impediment to deployment may have been the large quantities of expensive and hazardous chemicals that were required by the only available high-average-power lasers. This is now changing with recent advances in electrically powered lasers (both solid-state and free electron lasers). As these devices mature over the next few decades, they will enable practical military weapons at power levels ranging from kilowatts to megawatts. This evolution may be somewhat slowed or limited in the United States if there are policy concerns about the use of new types of weapons or about weaponization of space. As an example, the Department of Defense developed a microwave device for crowd control, called Active Denial, which has been shown to produce temporary pain without any injury. However, DoD was precluded from deploying it owing to policy (not legal) concerns. Other countries may not exhibit similar restraint, as evidenced by the open marketing of laser-blinding weapons despite a 1980 Geneva Convention prohibiting their development or use. Space offers the ideal environment for laser beam propagation; there is no atmosphere to either attenuate or spread the beam. As a result, large distances could be bridged quickly, with range limited by the size of the transmitting telescope and the potential damage mechanisms limited primarily by the laser's output power. Initial spacecraft laser weapons are conceivable within the next 20 years, with the potential for follow-on growth in laser power and transmitting telescope size. Transmitting telescope size would be limited by the spacecraft size and competing demands for weight and volume. Laser power could grow to the megawatt range as solid-state and free electron laser technology matures, but the major limitation to a spacecraft's weapon capability may prove to be its ability to generate and store the energy required by the laser and to store and dissipate the resultant waste heat.
