Light: Science & Applications (LSA) publishes high quality optics and photonics research from around the world. The Journal covers fundamental research as well as the important issues in engineering and applied sciences that are related to optics and photonics.
Lasers with a wavelength of two microns could move the boundaries of surgery and molecule detection. Researchers at EPFL have managed to generate such lasers using a simple and inexpensive method.
The method helps discovering the most efficient lamps, which may save billions in lighting costs in the future.
