THEL (Tactical High Energy Laser) For years, chemical-powered lasers were seen as the only viable alternative for weapons-strength ray guns. The most promising of those systems, the Tactical High Energy Laser, successfully shot down dozens of rockets and mortars. (this video shows it in action.) But generating the THEL's megawatts of laser power required hundreds of gallons of toxic chemicals — ethylene, nitrogen trifluoride. The weapons grew bulky (the small-scale version was only supposed to be kept in a mere right cargo containers, each 40 feet long). Worse, after a few shots, the lasers would have to be resupplied with a fresh batch of reactants. The logistics of hauling those toxins either through the air or across a battlefield made generals shiver. So, ultimately, interest swung back to solid state systems, like Yamamoto's, and, to a lesser extent, free electron lasers. http://www.defensetech.org/

first one to stare into it for 5 seconds is the winner!!!!

Works whith 747's?

did someone know that russia has more powerfull laser that burn 100 km2 and blind 500-700 km2 this awesome and i love this!!!!!

If you actually look at the results of many missile defense lasers they have depressingly low chances of success. Also this seems a little unrealistic, because during the test they knew when and from where each of the projectiles were being launched.

Cool, now we can shot down UFOs!!

Was this used in Lebanon war? looooool

They should have a fast version as AA counter IE On f-22, not only would it be hard to get a lock, but the missile wont reach the target

I have seen it on tv.

What makes you think that? If a laser pen can hit an aircraft in the sky, then this laser can easily destroy a projectile. The interceptor missiles compliment the lasers in the missile shield. The airborne laser (ABL) is meant to destroy missiles shortly after they're launched by hanging out in the war zone (like in between Iran and Israel). This system here has a different purpose, it is meant to kill small projectiles that are not worth firing a $500,000 missile at.

FYI mfisker, if the laser were 100% efficient and assuming all of it's energy came from combustion of liquid hydrogen, it would run a 10 megawatt laser for 1 liter per second. In reality various chemicals are combined in complex ways and the fuel's energy density is probably below 1%. Even at 1% it'd use 10 liters of fuel per second for a 1 megawatt laser. Even at 0.1% combustion efficiency, 100 liters of fuel per second for a 1 megawatt laser is good!
