Advances In Laser Research Opens Up Military Possibilities

Laser-Powered Warfare Lockheed's RELI laser, developed under a DARPA contract, works like an inverse prism to focus several different wavelengths of laser light. Lockheed Martin

In New Attempt to Build a Practical Military Laser Weapon, Lockheed Inverts a Prism -- Popular Science

Lasers can be powerful weapons — they can take down an aircraft at long ranges and in unstable conditions, for instance. But they are hampered by power and size limits, so they’re not widely used by the military (yet).

Lockheed Martin has a solution: a fiber laser that basically works like a backward prism.
