The 2018 Nobel Prize in Physics has been awarded to a trio of researchers for their work in developing powerful lasers.
Half of the prize money - worth nine million Swedish kronor ($1m or £770,000) - will go to Arthur Ashkin, a retired physicist who was the first to invent “optical tweezers” whilst working at Bell Labs. At 96, he is the oldest recipient of the prize to date.
Tweezers - Laser - Beams - Particles - Motion
Optical tweezers are fashioned from focused laser beams that can trap tiny particles inside. The motion of the light particles in the laser create pressure forces that can either keep the particles in place or nudge them elsewhere. They have been used to manipulate and study DNA, cells and viruses.
The rest of the cash will be split between Gérard Mourou, a retired physicist, and Donna Strickland, an associate professor at the University of Waterloo, Canada. They have been awarded "for their method of generating high-intensity, ultra-short optical pulses.” Strickland is only...
