High Energy Lasers getting ten times smaller and direct diode lasers

High Energy Lasers getting ten times smaller and direct diode lasers: "The goal of DARPA’s High-Energy Liquid Laser Area Defense System (HELLADS) is to develop a 150 kilowatt (kW) laser weapon system that is ten times smaller and lighter than current lasers of similar power, enabling integration onto tactical aircraft to defend against and defeat ground threats. DARPA recently completed laboratory testing of a fundamental building block for HELLADS, a single laser module that successfully demonstrated the ability to achieve high power and beam quality from a significantly lighter and smaller laser."
