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. Diode-pumped solid-state laser - Wikipedia

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

   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 ...

4. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   A green laser pointer is a frequency doubled Nd:YVO 4 diode-pumped solid state laser . [48] Nd:YAG can be also made to lase at its non-principal wavelength. The line at 946 nm is typically employed in "blue laser pointer" DPSS lasers, where it is doubled to 473 nm. [49] [50] [51]

5. Laser safety - Wikipedia

   en.wikipedia.org/wiki/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.

6. Lasers and aviation safety - Wikipedia

   en.wikipedia.org/wiki/Lasers_and_aviation_safety

   To give another example, of a more powerful laser—the type that might be used in an outdoor laser show: a 6-watt green (532 nm) laser with a 1.1 milliradian beam divergence is an eye hazard to about 1,600 feet (490 meters), can cause flash blindness to about 8,200 feet (1.5 mi/2.5 km), causes veiling glare to about 36,800 feet (7 mi; 11 km ...

7. Dazer Laser - Wikipedia

   en.wikipedia.org/wiki/Dazer_Laser

   Dazer Lasers use a "GreenStar Laser" (US Patent and Trademark Office provisional patent application no. 61/348,312), which is a diode-pumped solid-state (DPSS), 532 nm (green), Class IIIb laser that produces maximum power of over 750 mW without having to increase the same laser's size. [4]
