    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.

  6. 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.

    en.wikipedia.org/wiki/AN/PEQ-15

    The ATPIAL AN/PEQ-15 is a multifunctional laser aiming module that emits both visible and IR laser light for precise weapon aiming and produces IR light with an Illuminator for target/area illumination.

  8. 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 ...
