Researchers at Yale University have unveiled the very initial anti-laser in the world, and though its different uses are yet to be defined, it has been indicated that its applications would be in computers and radiology.
The “nega-laser” or Doppelganger was developed by two Yale scientists, A. Douglas Stone and Hui Cao. It is said to do the opposite of what laser technology does, whereby lasers generally produce a constant radiating beam in a mono-direction.
The anti-laser instead picks up that constant emission of light and links with it so as to destroy the beam through absorption. Scientists are confident that this new development could be integral in fighting the cancer scourge.
Lasers have a numerous number of uses in this day, from cosmetic and eye surgery to optical disc players, scanners and even in agriculture.
Douglas Stone agrees with a number of other physicists who have termed the anti-laser as a CPA – Coherent Perfect Absorber; and with the laser having been amongst the most important inventions of the earlier century, the anti-laser may just have that much impact in the future.
It’s been speculated that the anti-laser may be employed in the making of next generation super-computers that will be based on light components as an alternative to electrons.
One of the key features of the anti-laser is that it enables wavelength adjustment to control the amount of laser light absorbed, thereby working as an Off/On light switch.
