  3. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    Pulsed lasers which provide a high-power burst of energy for a short period are very effective in some laser cutting processes, particularly for piercing, or when very small holes or very low cutting speeds are required, since if a constant laser beam were used, the heat could reach the point of melting the whole piece being cut.

    These devices can generate high power outputs with good beam quality, wavelength-tunable narrow-linewidth radiation, or ultrashort laser pulses. In 2012, Nichia and OSRAM developed and manufactured commercial high-power green laser diodes (515/520 nm), which compete with traditional diode-pumped solid-state lasers.

  5. Laser safety - Wikipedia

    en.wikipedia.org/wiki/Laser_safety

    Moderate and high-power lasers are potentially hazardous because they can burn the retina, or even the skin. To control the risk of injury, various specifications, for example 21 Code of Federal Regulations (CFR) Part 1040 in the US and IEC 60825 internationally

  6. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    Dubbed "Burning Lasers", these are designed to burn through light plastics and paper, and can have very similar external appearances to their low-power counterparts. Because of their high power, many online retailers have warned high-power laser pointer users not to point them at humans or animals.
