General Atomics revealed in April 2015 that its Gen 3 High Energy Laser (HEL) completed beam quality and power measurements tests. The Gen 3 laser has a number of upgrades that provide improved beam quality, increased electrical to optical efficiency, and reduced size and weight; the assembly is small at only , and is powered by a compact Lithium-ion battery to demonstrate deployability on tactical platforms. Beam quality remained constant through the 30-second demonstration, proving that the beam quality of electrically-pumped lasers can be maintained above 50 kilowatts. General Atomics plans to have the laser module deployable on their Avenger unmanned aerial vehicle by 2018. Demonstrating sufficient laser power and beam quality ended the program's laboratory development phase and achieved acceptance for field trials. Ground-based field testing will assess its effects against rockets, mortars, vehicles, and surrogate surface-to-air missiles.
