  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. Laser - Wikipedia

    en.wikipedia.org/wiki/Laser

    Lasers are usually labeled with a safety class number, which identifies how dangerous the laser is: Class 1 is inherently safe, usually because the light is contained in an enclosure, for example in CD players; Class 2 is safe during normal use; the blink reflex of the eye will prevent damage. Usually up to 1 mW power, for example, laser pointers.

  4. 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 ...

    en.wikipedia.org/wiki/Titanium-sapphire_laser

    Titanium-sapphire lasers (also known as Ti:sapphire lasers, Ti:Al 2 O 3 lasers or Ti:sapphs) are tunable lasers which emit red and near-infrared light in the range from 650 to 1100 nanometers. These lasers are mainly used in scientific research because of their tunability and their ability to generate ultrashort pulses thanks to its broad light ...

  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. Beam expander - Wikipedia

    en.wikipedia.org/wiki/Beam_expander

    Initially multiple-prism grating configurations were introduced in narrow-linewidth liquid dye lasers [1] [7] but eventually were also adopted in gas, solid-state, and diode laser designs. [3] The generalized mathematical description of multiple-prism beam expanders, introduced by Duarte , [ 8 ] is known as the multiple-prism dispersion theory .
