(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 ...

Physicists in France are the first to create a random laser in a cloud of cold atoms under laboratory conditions. The effect was first seen decades ago in stellar clouds and the team believes that its ...

At its most basic level, a random laser is precisely what its name implies; random. It's random in the spectrum of light it produces and in the way that light is emitted. So, how do you control some ...

A random array of holes etched in a semiconductor structure, consisting of a periodic series of thin layers, has been demonstrated that emits mid-infrared laser radiation. The device could have ...

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 team of international scientists has developed a laser that can generate 254 trillion random digits per second, more than a hundred times faster than computer-based random number generators (RNG).

Using a single, chip-scale laser, scientists have managed to generate streams of completely random numbers at about 100 times the speed of the fastest random-numbers generator systems that are ...

Random Lasers are tiny structures emitting light irregularly into different directions. Scientists have now shown that these exotic light sources can be accurately controlled. Random Lasers are tiny ...
