  1. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a ...

  2. Laser safety - Wikipedia

    en.wikipedia.org/wiki/Laser_safety

    Laser safety. Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.

  3. Lasers and aviation safety - Wikipedia

    en.wikipedia.org/wiki/Lasers_and_aviation_safety

    Lasers and aviation safety. Lasers are one of the main threats of aviation safety. Under certain conditions, laser light or other bright lights (spotlights, searchlights) directed at aircraft can be a hazard. The most likely scenario is when a bright visible laser light causes distraction or temporary flash blindness to a pilot, during a ...

    Another military use of lasers is as a laser target designator. This is a low-power laser pointer used to indicate a target for a precision-guided munition, typically launched from an aircraft. The guided munition adjusts its flight-path to home in to the laser light reflected by the target, enabling a great precision in aiming.

    Greater than 1W power can be reached when the frequency doubling is resonator enhanced, resulting in Watt-class sources spanning across the visible spectrum, including a 400 nm blue laser with 2.6 W of output power. [25] Violet DPSS laser pointers (120 mW at 405 nm) use a direct diode infrared gallium arsenide (1 W @ 808 nm) lasers being ...
