The color wavelengths of visible laser beams from short to long are: blue violet (405nm), blue (445nm, 460nm, 473nm), green (532nm), yellow (589nm) and red (635nm, 650nm).
The wavelength determines the color and visibility of the laser beam.
UV radiation has a shorter wavelength than violet visible light. The wavelength of invisible infrared laser (780nn, 808nm, 850nm, 980nm, 1064nm…) is longer than that of visible red light.
Since the 20th century, the laser is another major invention of mankind after nuclear energy, the computer, and semiconductor. It is known as "the fastest knife", "the most accurate ruler" and "the brightest light". Laser wavelength refers to the output wavelength of a laser, which is an important parameter of laser beam output.
Visibility laser wavelength
The color wavelengths of visible laser beams from short to long are blue violet (405nm), blue (445nm, 460nm, 473nm), green (532nm), yellow (589nm), and red (635nm, 650nm). Lasers within this wavelength range are usually used in industrial and medical fields.
Invisible laser wavelength
The wavelength of the invisible infrared laser is 808nm, 980nm, and 1064nm respectively. The infrared laser of this frequency wavelength can emit the speed of infrared laser which can't be seen by the naked eye. The main application fields are industry and scientific research. In addition, it can also play an important role in the field of military defense and communication lighting.
The laser is a special kind of light. It has the characteristics of light, but it has purer color and greater energy than ordinary light. The wavelength of the laser is the same as that of ordinary light, from infrared to ultraviolet, there is violet light. The wavelength is about several thousand nanometers, the closer to the ultraviolet region, the shorter the laser wavelength, which can reach hundreds of nanometers or even smaller. Different wavelengths and frequencies are applied to different development fields, bringing new breakthroughs for daily life and scientific and technological development.
