  3. 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.

  4. Laser designator - Wikipedia

    en.wikipedia.org/wiki/Laser_designator

    A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively.

  5. Laser peening - Wikipedia

    en.wikipedia.org/wiki/Laser_peening

    Laser peening uses the dynamic mechanical effects of a shock wave imparted by a laser to modify the surface of a target material. It does not utilize thermal effects. Fundamentally, laser peening can be accomplished with only two components: a transparent overlay and a high-energy pulsed laser system.

  6. Directed-energy weapon - Wikipedia

    en.wikipedia.org/wiki/Directed-energy_weapon

    A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel , missiles , vehicles, and optical devices.

  7. Laser guidance - Wikipedia

    en.wikipedia.org/wiki/Laser_guidance

    Laser guidance is used by military to guide a missile or other projectile or vehicle to a target by means of a laser beam, either beam riding guidance or semi-active laser homing (SALH). With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known as ...

  8. List of laser applications - Wikipedia

    en.wikipedia.org/wiki/List_of_laser_applications

    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.
