In March 2009, under the JHPSSL program, Northrop Grumman said it had coaxed a solid-state laser past the 100KW mark -- a record for an electric laser. It got there by combining seven laser chains, each producing about 15KW of power, to produce a single beam of 105.5KW. Note that the 100KW level is generally considered the threshold for "weapons-grade" lasers.
At that time, the seven-chain JHPSSL laser demonstrator ran for more than five minutes, with beam quality of better than 3.0. As of December 2010, the system had logged more than six hours of operating time at power levels greater than 100KW.
