2. Laser pointer - Wikipedia

   en.wikipedia.org/wiki/Laser_pointer

   Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. 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.

   On March 28, 2008, a coordinated attack took place using four green laser pointers aimed at six aircraft landing at Sydney airport in New South Wales, Australia. As a result of this attack plus others, a law was proposed in mid-April 2008 in New South Wales to ban possession of handheld lasers, including low-power classroom pointers.

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 . 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.

   Half the reported strikes occurred at altitudes of less than 6,000 feet, and nearly 5% of strikes were reported at altitudes of 1,000 feet or lower. Green laser pointers are the most commonly...

   Exposure to hand-held laser light under such circumstances may seem trivial given the brevity of exposure, the large distances involved and beam spread of up to several metres. However, laser exposure may create dangerous conditions such as flash blindness .

   The most common DPSSL in use is the 532 nm wavelength green laser pointer. 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 ...
