Scientists get peacock feathers to emit laser light after adding dye and green pulses, revealing surprising biophotonic ...

(Nanowerk News) Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources ...

Like a pinball game in the hands of a good player, a collection of obstacles randomly positioned can be sufficient to trap light without the need for an optical cavity. By adding amplification, at no ...

The first ever random laser that uses liquid crystals to tune its emission has been developed by researchers at the University of Florence, Italy (Nature 414 708). In a random laser, multiple random ...

Using “random lasers” as a source of illumination in medical imaging equipment could improve both processing time and the clarity of the final images, according to new research by Yale University ...

A new laser that emits different wavelengths at different temperatures could be used in fields ranging from optoelectronics to remote heat sensing. Diederik Wiersma and Stefano Cavalieri of the ...

A directional random laser mediated by transverse Anderson localization in a disordered glass optical fiber is reported. Previous demonstrations of random lasers have found limited applications ...
