Are there blue laser pointers?

Blue laser pointers, which became available around 2006, have the same basic construction as DPSS green lasers. They most commonly emit light at 473 nm, which is produced by frequency doubling of 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal.

Is Blue Laser illegal?

Federal rules for those owning or using lasers in the U.S. In the U.S., it is legal under federal law to own a laser of any power.

Can blue lasers blind?

High-power blue-laser gadgets readily available online and increasingly popular among teens and young adults can cause serious, sometimes irreversible, eye damage. The injuries included four perforations of the retina, the nerve-rich, light-sensitive innermost layer of the eye responsible for detailed central vision.

Can a blue laser blind you?

Laser pointers can put out anywhere between 1 and 5 milliwatts of power, which is enough to damage the retina after 10 seconds of exposure. This can lead to permanent vision loss.
