ONCE again, science fiction has predicted science fact. Remember those movies where the hero (or villain) uses a beam from a compact laser to blow a rocket out of the sky? Last December, that generic bit of sci-fi drama took a step closer to reality. In a demonstration at the White Sands Missile Range in New Mexico, the solid-state heat-capacity laser (SSHCL) burned a 1-centimeter-diameter hole straight through a 2-centimeter-thick stack of steel samples in 6 seconds. The electrical current to do so came from a wall outlet and cost no more than 30 cents. While large chemical lasers have successfully shot down tactical rockets, the SSHCL design supports the weight and size requirements for a future mobile deployment.
The SSHCL, designed and developed at Lawrence Livermore, is the prototype of a laser tactical weapon, which shows promise as the first high-energy laser compact enough in size and weight to be considered part of the Army
