Technion-Israel Institute of Technology researchers have introduced a laser-resonator design inspired by the work of Arthur Ashkin. Created by graduate student Jacob Kher-Alden under the supervision of Tal Carmon, associate professor and head of the Optomechanics Center at Technion, the floating resonator design achieved 10 million circulations of light.
The resonator is made of a tiny drop of highly transparent oil of about 2 µm in diameter.
Optical resonators are commonly constructed of mirrors, to multiply reflected light. The more mirrors in a system, the closer the resonator’s shape resembles a circle, allowing light to circulate. Creating a spherical structure to allow light to rotate on all planes, passing…READ MORE
