  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. Diode-pumped solid-state laser - Wikipedia

    en.wikipedia.org/wiki/Diode-pumped_solid-state_laser

    A powerful (>200 mW) 808 nm wavelength infrared GaAlAs laser diode pumps a neodymium-doped yttrium aluminium garnet (Nd:YAG) or a neodymium-doped yttrium orthovanadate (Nd:YVO 4) crystal which produces 1064 nm wavelength light from the main spectral transition of neodymium ion.

  7. 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.

  8. Laser safety - Wikipedia

    en.wikipedia.org/wiki/Laser_safety

    In the period from 1999 to 2016, increasing attention has been paid to the risks posed by so-called laser pointers and laser pens. Typically, the sale of laser pointers is restricted to either class 3A (<5 mW) or class 2 (<1 mW), depending on local regulations.
