  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. Magneto-optical trap - Wikipedia

    en.wikipedia.org/wiki/Magneto-optical_trap

    The lasers needed for the magneto-optical trapping of rubidium 85: (a) & (b) show the absorption (red detuned to the dotted line) and spontaneous emission cycle, (c) & (d) are forbidden transitions, (e) shows that if the cooling laser excites an atom to the = state, it is allowed to decay to the "dark" lower hyperfine, F=2 state, which would ...

  4. ALPHA experiment - Wikipedia

    en.wikipedia.org/wiki/ALPHA_experiment

    The Antihydrogen Laser Physics Apparatus (ALPHA), also known as AD-5, is an experiment at CERN's Antiproton Decelerator, designed to trap antihydrogen in a magnetic trap in order to study its atomic spectra. The ultimate goal of the experiment is to test CPT symmetry through comparing the respective spectra of hydrogen and antihydrogen. [1]

  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 ...

  8. Lasers and aviation safety - Wikipedia

    en.wikipedia.org/wiki/Lasers_and_aviation_safety

    A key group inside the U.S. working on laser and aviation safety is the Society of Automotive Engineers (SAE) G-10T, Laser Safety Hazards Subcommittee. It consists of laser safety experts and researchers, pilots and other interested parties representing military, commercial and private aviation, and laser users.

  9. Optical tweezers - Wikipedia

    en.wikipedia.org/wiki/Optical_tweezers

    Ray optics explanation (focused laser). In addition to keeping the bead in the center of the laser, a focused laser also keeps the bead in a fixed axial position: The momentum change of the focused rays causes a force towards the laser focus, both when the bead is in front (left image) or behind (right image) the laser focus.
