The 1064 nm wavelength of Nd:YAG is thought to be particularly dangerous, as it is invisible and initial exposure is painless. [40] The Chinese ZM-87 blinding laser weapon uses a laser of this type, though only 22 have been produced due to their prohibition by the Convention on Certain Conventional Weapons. North Korea is reported to have used ...

Consequently, green ink tattoos may require treatment with 755 nm light but may also respond to 694 nm, 650 nm and 1064 nm. Multiple wavelengths of light may be needed to remove colored inks. One small Greek study showed that the R20 method—four passes with the laser, twenty minutes apart—caused more breaking up of the ink than the ...
Furthermore, some lasers emit more than one wavelength of light, and this may be a particular problem with some less expensive frequency-doubled lasers, such as 532 nm "green laser pointers" which are commonly pumped by 808 nm infrared laser diodes, and also generate the fundamental 1064 nm laser beam which is used to produce the final 532 nm ...
An Nd:YAG laser (1064 nm wavelength) is a common choice of laser for working with biological specimens. This is because such specimens (being mostly water) have a low absorption coefficient at this wavelength. [43]

In continuous-wave laser applications, however, BiBO may exhibit instabilities which degrade its performance. [4] Yellow DPSSLs use an even more complicated process: An 808 nm pump diode is used to generate 1,064 nm and 1,342 nm light, which are summed in parallel to become 593.5 nm. Due to their complexity, most yellow DPSSLs are only around 1 ...
The laser drilling process involves the use of an infrared laser (of surgical grade at a wavelength about 1064 nm) to bore very fine holes (around 0.02 millimeters in diameter) into a diamond to create a route of access to a black carbon crystal inclusion.
