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 ...

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 ...

Working with physicists from the University of Rome, a team led by Professor Cordt Zollfrank from the Technical University of Munich (TUM) built the first controllable random laser based on cellulose ...

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, making what could be an ...

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 ...

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).
