Target for Military Laser

<< >>
Description
Potential military uses for lasers have attracted both government funding and popular interest. While laser ”ray guns” remain in the realm of science fiction, significant research has been conducted toward that goal. In the 1980s, tests of a deuterium-fluoride (or DF) chemical laser were conducted at the U.S. Army's Redstone Arsenal. A chemical reaction created the energy necessary to generate a laser beam. As this object shows, that beam can be quite powerful.
In 1985, the Army transferred this test target to the Smithsonian. The target consists of six steel plates, each about 2 mm thick, bolted together. A hole of decreasing diameter is burned through the target from front to back. Information provided with the target reported that a 130 kilowatt laser illuminated the target from a distance of 60 meters for 5 seconds.
