The Best Defense Is a Bright Diode Laser

Facebook X LinkedIn Email
Diode lasers are widely deployed as pumps for other lasers, and there are increasing military applications in which the diode laser beam is used directly.

Dr. Paul Rudy, Quintessence Photonics Corp.

Throughout history, military applications have employed state-of-the-art technologies as conflicting parties hastened to stay one step ahead of each another. Photonics technology is no exception. As early as 212 B.C., optics were used as a weapon when, according to legend, Archimedes used large bronze mirrors to direct and focus sunlight, setting Roman ships ablaze during the battle of Syracuse. Figure 1. Lasers have found a place in high-precision target designation. With increased spatial brightness, diode lasers may become suited for airborne target designation. In the past several...Read full article

    electromagnetic radiation
    Radiation emitted from vibrating charged particles. A combination of oscillating electrical and magnetic fields that propagates through otherwise empty space with the velocity of light. This constant velocity equals the alternation frequency multiplied by the wavelength; hence, the frequency and wavelength are inversely proportional to each other. The spectrum of electromagnetic radiation is continuous over all frequencies.
