Laser pointer users should not point laser beams at aircraft, moving vehicles, or towards strangers. [33] Since laser pointers became readily available, they have been misused, leading to the development of laws and regulations specifically addressing use of such lasers. Their very long range makes it difficult to find the source of a laser spot.
In the U.S., the Congressional Research Service notes that a ban could "pose significant challenges because these devices are widely available at low cost and are used in a variety of applications such as laser pointers, laser levels and laser gun sights." [19] Requiring review or approval of outdoor laser uses.
Low to medium power laser diodes are used in laser pointers, laser printers and CD/DVD players. Laser diodes are also frequently used to optically pump other lasers with high efficiency. The highest-power industrial laser diodes, with power of up to 20 kW, are used in industry for cutting and welding. [75]
Laser pointers, even those sold for less than $20 online, can distract pilots or cause flash blindness — of particular danger during takeoff and landing, when many incidents are reported ...
Blue DPSS laser pointers, initial availability around 2006, have the same basic construction as DPSS green lasers. They most commonly emit light at 473 nm, which is produced by frequency doubling of 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal. [ 24 ]
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
