  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. Scientists program lab mice into killing machines using lasers

    en.wikipedia.org/wiki/Outline_of_biophysics

    Molecular biophysics – interdisciplinary field that applies methods and concepts from physics, chemistry, engineering, mathematics and biology [4] to understand biomolecular systems and explain biological function in terms of molecular structure, structural organization, and dynamic behaviour at various levels of complexity, from single ...

  5. 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.

  7. 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 ...

  8. Hazards of synthetic biology - Wikipedia

    en.wikipedia.org/wiki/Hazards_of_synthetic_biology

    Microbiology laboratories present multiple chemical, biological, and physical hazards that can be mitigated with laboratory safety methods. Biosafety hazards to workers from synthetic biology are similar to those in existing fields of biotechnology, mainly exposure to pathogens and toxic chemicals used in a laboratory or industrial setting.

  9. Filament propagation - Wikipedia

    en.wikipedia.org/wiki/Filament_propagation

    The short pulse laser beam having a wavelength to which the work is transparent is directed to the front surface of the work toward the back surface and focused. A filament in the light beam traveling direction from the beam waist is formed by the auto-focusing action due to the laser beam propagation in the work is formed.
