What is Nanolaser?

Nanolaser has all the typical features of standard size laser, which means that light is amplified by stimulated radiation emissions. The primary difference with Nanolaser is the measure of the mechanism and light beam that is emitted. The "nano" prefix is ​​derived from the Greek word, which means "dwarf". In accordance with this, NanoLaser is much smaller than a standard laser, both in the track and the emitted beam. In fact, most nanotechnologies are often tens or hundreds of times less than traditional technology.

Nanolasers have the ability to condense or reduce the light beam emitted outside the diffraction limit of light. As a scientific concept, the diffraction limit of light concerns the ability to reduce light. Suddenly, scientists believed that light could be limited to a maximum of half of their wavelength. Such limits were considered a diffraction limit of light. Unlike traditional lasers, however, nanolasers are able to reduce the light beam100 times less than half of the wavelength.

Lasers work through a complex relationship between visible light, photons and wavelengths. To create photon oscillation, which is necessary for the laser to emit light, optical resonators are required, components used to control feedback in the laser. Before developing nanolaser technologies, the minimum resonator size was considered to be half the wavelength of the laser light. By using superficial plasms rather than photons, developers were able to reduce the size of the resonator desired for nanolasers, creating the smallest lasers in the world.

The first working Nanolaser was developed in 2003. Designs and proposals for technology technologies began at the end of the 1950s, although the initial miniature plasmon lasers proved impractical. Since 2003, numerous progress and improvement in the technology of the nano -serviceness of the king has led. Since 2011, the smallest nanolaser was known as a spaser, whileThe name is an abbreviation for "amplification of the plasmon surface with a stimulated emission of radiation".

applications for these small lasers include computers, consumer electronics, medical applications and microscopes to name at least some. For example, spasers have the ability to be small enough to fit into a computer chip, allowing information to be processed via the lights of versus electrons. Nanotechnologies using semiconductor lasers, collectively known as biomedical microdevices, have been developed. These nanolaser biomedical devices allow scientists to recognize cancer cells from healthy cells using nanotechnology.
