Despite the major difficulties of producing such weapons, a number of military leaders are optimistic that at least a modestly practical version can be built. S. Air Force, for instance, is confident that its ongoing development of the so-called Airborne Laser (ABL) will result in a working weapon within four to six years. “The job of the ABL,” reports military weapons observer John Tirpack, will be to orbit the skies near the forward edge of a battle area, watching with infrared search-andtrack devices for the launch of enemy .

Breck Hitz, an expert on industrial lasers, elaborates: Lasers are used to cut, drill, weld, heat-treat, and otherwise alter both metals and nonmetals. Lasers can drill tiny holes in turbine blades more quickly and less expensively than mechanical drills. Lasers have several advantages over conventional techniques of cutting materials. For one thing, unlike saw blades or knife blades, lasers never get dull. For another, lasers make cuts with better edge quality than most mechanical cutters. The edges of metal parts cut by a laser rarely need to be filed or polished because the laser makes such a clean cut.

But even the frequency of television signals is small compared to beams of light. Visible light frequencies range between 400 trillion and 800 trillion cycles per second. That means that light has the capacity to carry more than a million times as much information as television. In communications, the amount of information exchanged is the most important factor. It is no wonder then that the laser, which uses light to transmit information, has been so revolutionary. Sending Signals Through Air and Cables Such laser-based communications work in two basic ways.
