Turning loss to gain: cutting power could boost laser output

October 27, 2014

Prof. Hakan Tureci (together with Grad Student Omer Malik and Li Ge, Assistant Professor at the City University of New York) have shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.
 
The finding, published Oct. 26 in the journal Nature Photonics, could allow far more sensitive and energy-efficient lasers, as well as potentially more control over the frequencies and spatial pattern of light emission.  Complete article can be found here
