Three scientists have been awarded the 2018 Nobel Prize in physics for creating groundbreaking tools from beams of light.
Arthur Ashkin won this esteemed prize, for his development of “optical tweezers”, technology that allows scientists to grab atoms, viruses and bacteria in finger-like laser-beams.
Gérard Mourou, and Donna Strickland, each receive a quarter of the prize for work that paved the way for the shortest, most intense laser beams ever created. Their technique named "chirped pulse amplification".
The amplification technique of the Chirped Pulse Amplification (CPA) lasers was developed a little more than 30 years ago by Gérard Mourou and Donna Strickland, who was his student at the time, the technique creates ultrashort, intense bursts of laser light by stretching, amplifying and finally recompressing the light waves. Adapted to the medical field, the (CPA) technique has led to new advances in the field of refractive surgery of the eye and cataracts. "The inventions that are honored this year have revolutionized the physics of lasers".
