Boeing's new laser cannon can melt a hole in a tank from five miles away and 10,000 feet up—and it’s ready to fly this year. Its downright scary

following is copied from:www.popsci.com/files/imagecache/article_image_large/files/articles/hiw_laser_485

How to Melt a Tank in Three Seconds Or Less
1. Find Your Target
When the C-130 flies within targeting range (up to five miles away), the gunner aims using a rotating video camera mounted beneath the fuselage. The computer locks onto the object to continually track it. A second crew member precisely adjusts the laser beam’s strength—higher power to disable vehicles, lower power to knock out, say, a small power generator. The gunner hits “fire,” and the computer takes over from there.
2. Heat Up the Laser
In a fraction of a second, chlorine gas mixes with hydrogen peroxide. The resulting chemical reaction creates highly energetic oxygen molecules. Pressurized nitrogen pushes the oxygen through a fine mist of iodine, transferring the oxygen’s energy to iodine molecules, which shed it in the form of intense light.
3. Amplify the Beam
The optical resonator bounces this light between mirrors, forcing more iodine molecules to cough up their photons, further increasing the laser beam’s intensity. From there, the light travels through a sealed pipe above the weapon’s crew station and into a chamber called the optical bench. There, sensors determine the beam’s quality, while mechanically controlled mirrors compensate for movement of the airplane, vibration and atmospheric conditions. Precise airflow regulates the chamber’s temperature and humidity, which helps keep the beam strong.
4. Stand Clear
A kind of reverse telescope called the beam expander inside a retractable, swiveling pod called the turret widens the beam to 20 inches and aims it. The laser’s computer determines the distance to the target and adjusts the beam so it condenses into a focused point at just the right spot. Tracking computers help make microscopic adjustments to compensate for both the airplane’s and the target’s movement. A burst of a few seconds’ duration will burn a several-inch-wide hole in whatever it hits.
How hot is the beam? The laser itself isn’t hot, but it can heat its target to thousands of degrees.
Does the laser sear everything in its path? Yes. If a bird flew into the firing laser’s line of sight—
well, no more bird. Fortunately, the weapon will fire for only a few seconds at a time, minimizing the risk.
Does it melt its target or just set it aflame? That depends on what it hits. It will melt metal, but if
the target is combustible, it will burn.

I want that coming out of my fingers.

What about the most overused meme in the history of memes? OTHER THAN RICKROLL, IT'S FUCKING DEAD. >:C
