Abstract :
Under the Joint High Power Solid-State Laser (JHPSSL) program, Northrop Grumman is developing a laser architecture that can scale to >100 kW with a near-term goal of a 25 kW demonstration. The laser concept uses a single master oscillator to drive parallel power-amplifier chains; output from the amplifier chains are tiled and phased (piston corrected) to provide a spatially coherent beam. Scaling is achieved by adding parallel amplifier chains.
