Japanese military laser

The Japanese military laser prototype is first seen in the complex where Kaneda and Kei are taken prisoner in the second book of Katsuhiro Otomo's manga Akira. It is the size of a RPG but instead of firing explosove rockets, it fires a laser, strong enough to harm and even kill Tetsuo and other psychics. Its power is limited, though. after a few shots of the laser it runs out of juices and can only fire small lasers that barely manage to light things on fire.
