UV Laser / Laser Ultravioletto (laser viola)

A violet laser has a wavelength bordering those of ultra-violet. Because the definition of ultra-violet is not clearly established, some people might call this a violet laser while others call it an ultra-violet laser.Actually,the wavelengths of violet light is 405nm. Yet other people call then Blu-ray lasers or HD-DVD lasers depending on the source and/or optical output of the diode. Usually a HD-DVD diode is incorrectly called a Blu-ray diode because it has became a commonly accepted term for the diodes of this color.

Ultraviolet laser products have many usage in scientific research, manufacturing, biotechnology and medical area. As we all know, the wavelength of Ultraviolet has characters of sterilization and disinfectant as lasers in the UV range have very destructive capabilities. The technology used in emitting Ultraviolet laser in laser pointers is very like micro-machining applications which often used in the manufacturing of printed circuit boards and consumer electronics.

Except the usage we talked at previous paragraph , UV lasers are also be used at OEM applications and other projects that require micro-precision machining. For example, in cosmetic dentistry UV lasers mainly used to facilitate chemical bonding and bleaching of organic enamels and other procedures. And also UV lasers are capable of performing experiments in atomic and molecular spectroscopy and chemical dynamics. Wavelengths emitted by UV lasers is shorter than blue lasers. So it's capable of producing 20 times as dense as the current Blu-ray lasers. In Japan, computer hardware manufacturers put UV lasers and ultraviolet diode emitters into computer data storage disk technology to increasing data storage capabilities drastically.

Now human beings spread Ultraviolet laser technology to a new generation of application in nanotechnology, material sciences, biology, chemistry, plasma physics and a myriad of other usages. Therefore, UV lasers become more and more important in humanal improvement.
