2. 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 ...

3. AN/PEQ-15 - Wikipedia

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

   The Advanced Target Pointer / Illuminator / Aiming Light, ATPIAL AN/PEQ-15 known colloquially as the "PEQ-15" [/ p ɛ k / / f ɪ f t iː n /] produced by L3Harris (originally designed and manufactured by Insight Technology, until their acquisition by L3Harris in 2010); is a multifunction IR Target Pointer & Illuminator, a.k.a. a Laser Aiming Module (LAM) for use as a rifle attachment, using a ...

4. Diode-pumped solid-state laser - Wikipedia

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

   A diode-pumped solid-state laser (DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode. DPSSLs have advantages in compactness and efficiency over other types, and high power DPSSLs have replaced ion lasers and flashlamp-pumped lasers in many scientific ...

5. List of laser applications - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_applications

   In science, lasers are used in many ways, including: A wide variety of interferometric techniques. Raman spectroscopy. Laser induced breakdown spectroscopy. Atmospheric remote sensing. Investigating nonlinear optics phenomena. Holographic techniques employing lasers also contribute to a number of measurement techniques.

6. 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 ...

7. 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.
