What is a blue laser?

Blue laser is a type of laser that seems to be a blue color. Its light emits a wavelength strip between 360 and 480 nanometers. These blue lasers can have applications from optoelectronic data storage to the medical area.

The blue laser discovered in Japan individual scientists and electronic societies. The result was an attempt to develop a blue light emitting diode (LED). Its successful development can be attributed to the use of Gallia nitride crystals rather than a zinc selenide, which was a normal course that previous scientists had completed in an attempt to develop a blue laser. Although blue lasers can technically provide light on wavelengths between 360 and 480 nanometers, blue lasers generally emit light on 400 nanometers.

Although many people referring to blue lasers have lasers that are really blue, blue lasers are narrow -related with purple lasers. In fact is popularThe "blue" laser, which works on 405 nanometers, actually purple. The public can confuse this purple laser with a blue laser because two types look very similar to the human eye. Looking at 405 nanometer light, people can confuse Florescence for blue; As a reference point, black lights can also deceive the human eye in the same way. We could say that people look at the real colors of blue light only when they watch the light with a wavelength between 450 and 460 nanometers.

There are many practical applications for blue lasers. Telecommunications, information technology, environmental monitoring, medical diagnostics and electronic equipment industry benefit from Blue Light lasers. Micropro -projectors and displays can use blue lasers for operational purposes.

Blue Lasers also changed the way consumers experience fun. The blue laser makes a high density (HD) a dimensional data technology of a gital disk (DVD) and Blu-ray ™ technology. Her shorter waveleLKA than other types of lasers is what provides this ability, as lasers of shorter wavelengths can read increased concentrations of discs from discs.

Standard laser indicators also come up with a blue laser option. These blue lasers can work with 473 nanometer wavelengths. For those who are tired of Red and green laser alternatives, the blue laser can provide a little uniqueness for laser use. However, because they use newer technology, blue lasers can be a more expensive choice.
