Battlefield Lasers

Incredibly cool news from the military technology front: Military Tests Laser Defense to Artillery.
"This is actually a very pivotal time in terms of high-powered laser systems," says Brent Dane, project manager for high-energy lasers at Lawrence Livermore Labs.
For about six years he and his team have been hard at work on a high-powered, portable, electric laser for the U.S. Department of Defense.
"If there's one sort of key aspect of a solid-state laser, it's mobility," Dane says. "And the mobility comes from a very high electrical efficiency and architectures which support compact, very lightweight designs."
Using special "beam director" software, a laser can lock onto an in-flight missile and heat the explosives inside their metal shell, causing them to detonate before they reach their target.
Lawrence Livermore Laboratories has just developed a 25-kilowatt laser and is working on a 100-kilowatt version, which Dane says will supply enough power to knock out a missile in two to three seconds.
The 100-kilowatt laser should be ready for combat by 2010, Dane says. However, the battlefield technology doesn't end with the lasers. The lasers will likely ride into battle atop hybrid electric Humvees.
"If you look at the typical traction battery that's being proposed for these hybrid electric vehicles," Dane says, "that battery will be adequate for actually powering a hundred-kilowatt laser system."
