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 ...
the laser operates at 1064 nm and has a pulse duration of 10 ns, 100 mJ/cm 2 (or 10 3 J/m 2). You have goggles that are specified as DIR 1064 LB5 . The pulse duration indicates that we should look at the R specification, with scale number n =5, which gives an upper limit of 5×10 2 J/m 2 , which means that these goggles do not offer suitable ...
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 ...

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 ...
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]
This is the case with 1064 nm laser designators used by JTACs as that wavelength of light is difficult to see under standard Gen III/III+ night vision devices. [2] Other imaging devices with "see-spot" capabilities to "see" the laser spot are often utilized to make sure the target is being correctly designated.
The first-generation Laser Interferometer Gravitational Wave Observatory was based on these lasers, operating at 1064 nm. [10] Two Lightwave nonplanar oscillators were launched into space in 2004 as components of NASA’s Tropospheric Emission Spectrometer , an earth-observing satellite instrument which was still operational in 2015.
