Boeing recently tested their new 25 kilowatt solid-state laser, which is a step in the direction of a future 100 kW (keep in mind the Death Star was only packing something like 80 kW*) ray that will blow up the whole world and possibly Mars and Venus (which, honestly, is a shitty planet that we're better off without).
The thin-disk laser is an initiative to demonstrate that solid-state laser technologies are now ready to move out of the laboratory and into full development as weapon systems. Solid-state lasers are powered by electricity, making them highly mobile and supportable on the battlefield.
A high-power solid-state laser will damage, disable or destroy targets at the speed of light, with little to no collateral damage, supporting missions on the battlefield and in urban operations.
Okay, I have no idea what that means because I'm not a scientist (I'm just a guy who looks sexy as hell in a white lab coat), but I think what they're saying is you shouldn't stare directly at it.
*I made that up so don't email me complaining about how the Death Star's superlaser was like 50,000 billion kW
