One of the latest inventions of US is world smallest laser. It is claimed that it is thousand times tinnier than a human hair. In the history of technology the laser is consider a most surprising fact of the world.
Where and why is it created?
The laser is great invention by researchers (Berkley, university of California). It is considered an enormous latest inventions of a nano laser in the field of optical technology. The nano laser can use to investigate and manipulate the factor of DNA. It will also improve the telecommunication sector and computer industry by made a supper largest computer.
Professor Zhang (University of California at Berkeley) Said:
“The Plasmon laser constrict light into a gap of only 5nm wide. The importance of laser is that it has a specific ability to apprehend the light with a limited period of time in a short space and it stabilize waves synchronized”
What is Plasmon?
Plasmon is in fact an electronic wave’s movement on the metal surface. Plasmon represents the capability of light source for small confinement.
The Daily California
In the news paper (the daily California) published an article about the latest inventions of laser. The headlines were “barely scientist has unveiled the world’s smallest laser which is thousand of time tinnier than a human hair and it is more than 100 times informative than a conventional laser.
This laser is consider as a smallest high energy laser which led to develop a smallest and faster technology.
Samuel Mao Said
who is one of a specialized scientist, worked on laser? Such types of laser which develop with new technology like a compact disc. Which memory capacity are hundred times greater and more informative.
Spaser Promises Ultrafast Nanocircuits
The world’s smallest laser is located in a silica globe that measures just 44 nanometres in diameter. It is 10 times the optical wavelength. This is not a typical laser, and It is the first-ever sparser. ‘
While a laser amplifies light with a mirror cavity to enhance it and a spacer amplifies the surface plasmons – tiny oscillations in the number of free electrons on the metal’s surface that generate the light wave.
The spacer can provide light sources to illuminate near-field optical microscopes that can resolve delicate information beyond conventional light microscopy and nanolithography capabilities, making patterns smaller than the hairs of a human. This device opens the way to nanoscale circuits that can perform information processing faster than microelectronic chips used in computers today.
