Gen 3 High Energy Laser Completes Beam Quality Evaluation
- HEL System Designed for Land, Sea, and Airborne Platforms
General Atomics Aeronautical Systems, Inc. (GA ASI), a leading manufacturer of Remotely Piloted Aircraft (RPA) systems, radars, and electro-optic and related mission systems solutions, today announced that an independent measurement team contracted by the U.S. Government has completed beam quality and power measurements of GA-ASI’s Gen 3 High Energy Laser System (HEL) using the Joint Technology Office (JTO) Government Diagnostic System (GDS).
“These measurements confirm the exceptional beam quality of the Gen 3 HEL, the next-generation leader in electrically-pumped lasers,” said Claudio Pereida, executive vice president, Mission Systems, GA-ASI.

The new laser represents the third generation of technology originally developed under the High Energy Liquid Laser Area Defense System (HELLADS, Gen 1) program. The Gen 3 Laser employs a number of upgrades resulting in improved beam quality, increased electrical to optical efficiency, and reduced size and weight. The recently certified Gen 3 laser assembly is very compact at only 1.3 x 0.4 x 0.5 meters. The system is powered by a compact Lithium-ion battery supply designed to demonstrate a deployable architecture for tactical platforms.
The Gen 3 HEL tested is a unit cell for the Tactical Laser Weapon Module (TLWM) currently under development. Featuring a flexible, deployable architecture, the TLWM is designed for use on land, sea, and airborne platforms and will be available in four versions at the 50, 75, 150, and 300 kilowatt laser output levels.
The GDS was employed by an independent measurement team to evaluate the beam quality of the Gen 3 system over a range of operating power and run time. According to JTO’s Jack Slater, “The system produced the best beam quality from a high energy laser that we have yet measured with the GDS. We were impressed to see that the beam quality remained constant with increasing output power and run-time.”
With run time limited only by the magazine depth of the battery system, beam quality was constant throughout the entire run at greater than 30 seconds. These measurements confirm that the exceptional beam quality of this new generation of electrically-pumped lasers is maintained above the 50 kilowatt level.
Following this evaluation, the independent team will use the GDS again to conduct beam quality measurements of the GA-ASI HELLADS Demonstrator Laser Weapon System (DLWS). The HELLADS DLWS includes a 150 kilowatt class laser with integrated power and thermal management.
