Blue Lasers and Its Major Uses

Technology has come a long way and it is making our lives easier by the day. Day in day out we are having new technological advancement that are adding on to our lives. Take for instance the blue lasers. This has come in handy and they are available in the market in numbers.

Blue lasers refer to a type of laser that has the capacity of emitting EM radiation that has a wavelength that ranges from 360 to 480 Nanometers. The lights that emanated from the blue lasers that are of wavelengths that are shorter at times looks violet when seen by the human eye, or seem to have a color that is distinctly different. Further developments in technology have led to production of a number of devices that are using the blue laser technology. The blue lasers that are available today use what is referred to as a surface of sapphire, and that is covered by a layer that is made of gallium nitride. This kind of technology has been widely applied by Japanese companies. The Blue lasers that are semiconductors use gallium nitride and have a single crystal surface, a technology that is used by a Polish Company.

We have Blue laser pointers, these were availed to the markets in the year 2006, and they have similar basic constructs as DPSS that are known as green lasers. A great number of people tend to confuse between violet lasers and blue lasers a great deal. This is owed to the fact that both of them when looked at by the human eye tend to look very similar. When you look at the light of 405 Nanometers one tends to mistake the florescent and consider it to be in blue color and tend to take that as a point of reference, thus one can come into a conclusion that one looks at blue light colors when they are only viewing light that has a wavelength of a range between 450- 460 nanometers.

Blue lasers have a wide range of applications. They are used in many fields in today’s world. They can be said to have versatile applications. They are used in the telecommunication industry, on the Information technology (IT), used in the monitoring environment, in the medical sector to undertake medical diagnostics. They also find applications in a number of other electrical equipments. The small projector displays also use the blue light lasers in their operations and they ensure stability efficiency and high reliability.

With the application of blue lasers in number of home consumer use, have made home users to experience some form of entertainment. It has the capacity of making high density DVDs and has also made it possible to store data in the blue ray. The laser rays that have shorter wavelengths are the ones used for these purposes. Blue lasers that have a short wavelength can read information concentrated on the discs.
