  2. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    In 2012, Nichia and OSRAM developed and manufactured merchant high-power green laser diodes (515/520 nm), which can emit green laser directly. Because even a low-powered green laser is visible at night through Rayleigh scattering from air molecules, this type of pointer is used by astronomers to easily point out stars and constellations.

    en.wikipedia.org/wiki/Dazzler_(weapon)

    The green laser is chosen for its unique ability to react with the human eye. Dazzlers maintain eye safety by producing diverging light that is less coherent (focused) than typical lasers. This produces a larger, less concentrated spot at greater distances which is easier to aim at longer distances and retains the desired effect on targets.

    A blue or red laser will appear much dimmer—and thus less distracting—than a green or yellow laser of equal power. For example, a 10-watt continuous-wave yttrium aluminium garnet laser at 532 nanometers (green) can appear brighter to the eye than an 18-watt continuous-wave argon-ion laser that outputs 10 watts of 514 nm (green-blue) light ...

    The most common DPSSL in use is the 532 nm wavelength green laser pointer. 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 ...
