Blue Laser

Definition - What does Blue Laser mean?

Blue laser is a laser with a shorter wavelength, on the order of 360 to 48 nm of electromagnetic radiation. The shorter wavelength makes it appear blue to the human eye. Blue lasers have a shorter wavelength than the most commonly used red lasers. They can be produced using gases, indium gallium, infrared or diode lasers, all of which operate in the blue wavelength. Blue lasers have a higher storage capacity, and are used in a wide range of applications in telecommunications, computer storage and printing technology.

Techopedia explains Blue Laser

A laser is a focused beam of light where the beam consists of rays of only one wavelength. The intensity of laser beams is many times higher than that of regular light beams. As photons of a particular wavelength are concentrated to form a laser, it is marked by a distinct color, depending on the wavelength. In the case of blue lasers, this wavelength range exists between 360 and 480 nm.

Laser beams are produced using special techniques, which usually involve a special substance through which photons are produced and released as a focused beam of laser. Photons are produced by means of a chemical reaction on a particular substance that emits photons of a particular wavelength, which are then concentrated using a tube and reflective mirrors to produce an intense beam of light. Energy is added to the usual light by this process, and the resulting laser light can be intense enough to even cut through metal.

Blue laser diodes were invented by the Japanese inventor Shuji Nakamura. Some substances used in the production of blue lasers include helium-cadmium gas, argon-ion gas, gallium nitride, etc. They can also be produced using infrared lasers or diode-pumped solid-state lasers. The most commonly used blue lasers are gallium nitride lasers.

Blue lasers are used in Blu-ray, which is used as a storage standard in DVD and related applications. Blue lasers also have a wide scope of application in printing, as they allow for a higher resolution compared to the red lasers used in laser printers.
