  2. 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.

  3. Multiangle light scattering - Wikipedia

    en.wikipedia.org/wiki/Multiangle_light_scattering

    A collimated beam from a laser source is most often used, in which case the technique can be referred to as multiangle laser light scattering (MALLS). The insertion of the word laser was intended to reassure those used to making light scattering measurements with conventional light sources, such as Hg-arc lamps that low-angle measurements could ...

  4. 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 ...

  5. Laser damage threshold - Wikipedia

    en.wikipedia.org/wiki/Laser_damage_threshold

    The laser damage threshold (LDT) or laser induced damage threshold (LIDT) is the limit at which an optic or material will be damaged by a laser given the fluence (energy per area), intensity (power per area), and wavelength. LDT values are relevant to both transmissive and reflective optical elements and in applications where the laser induced ...

  6. Biophotonics - Wikipedia

    en.wikipedia.org/wiki/Biophotonics

    Imaging in biophotonics often relies on laser light, and integration with biological systems is seen as a promising route to enhancing sensing and imaging techniques. Biolasers, like any lasers, require three components: a gain medium, an optical feedback structure and a pump source.

  7. RP Photonics Encyclopedia - Wikipedia

    en.wikipedia.org/wiki/RP_Photonics_Encyclopedia

    The RP Photonics Encyclopedia (formerly Encyclopedia of Laser Physics and Technology) is an encyclopedia of optics and optoelectronics, laser technology, optical fibers, nonlinear optics, optical communications, imaging science, optical metrology, spectroscopy and ultrashort pulse physics. [1] It is available online as a free resource.

  8. List of laser types - Wikipedia

    en.wikipedia.org/wiki/List_of_laser_types

    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).

  9. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    The results of the evaluation help to assess possible hazards to the safety and health of workers and to define protective measures. Since electromagnetic fields may influence passive or active implants of workers, it is essential to consider the exposure at their workplaces separately in the risk assessment .
