  3. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.

    en.wikipedia.org/wiki/Diode-pumped_solid-state_laser

    A powerful (>200 mW) 808 nm wavelength infrared GaAlAs laser diode pumps a neodymium-doped yttrium aluminium garnet (Nd:YAG) or a neodymium-doped yttrium orthovanadate (Nd:YVO 4) crystal which produces 1064 nm wavelength light from the main spectral transition of neodymium ion.

  7. Dye laser - Wikipedia

    en.wikipedia.org/wiki/Dye_laser

    Dye laser. A dye laser is a laser that uses an organic dye as the lasing medium, usually as a liquid solution. Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to 100 nanometers or more. The wide bandwidth makes them particularly suitable for tunable lasers ...

  8. Laser safety - Wikipedia

    en.wikipedia.org/wiki/Laser_safety

    In the period from 1999 to 2016, increasing attention has been paid to the risks posed by so-called laser pointers and laser pens. Typically, the sale of laser pointers is restricted to either class 3A (<5 mW) or class 2 (<1 mW), depending on local regulations.
