In recent test-blasts, Pentagon-researchers at Northrop Grumman managed to get its 105 kilowatts of power out of their laser — past the “100kW threshold [that] has been viewed traditionally as a proof of principle for ‘weapons grade’ power levels for high-energy lasers,” Northrop’s vice president of directed energy systems, Dan Wildt, said in a statement.

That much power won’t get you a Star Wars-style blaster. But it should be more than enough to zap the mortars and rockets that insurgents have used to pound American bases in Iraq and Afghanistan.
