Bose-Einstein-Light (BEL) - Generation of coherent light of high intensity in a solid state “cold Laser”

12.12.2014

Lasers as sources for coherent and intense light are used in many high-tech applications and medical devices. Generally, the generation of Laser-light is characterized by a significant level of optical and electrical energy input and low efficiency. Contrary to the Laser, BEL utilizes an organic dye/polymer system, which is arranged between two mirrors forming an optical micro-cavity. The incoming light is multiply reflected between the mirrors, giving rise to an effective photon mass and a confining potential - key prerequisites for the Bose-Einstein condensation of photons. Thermalisation is achieved by the photon scattering off the dye molecules, resulting in a strong light concentration effect into the centre of the confining potential, where the potential energy is minimized. The spatial concentration is a consequence of the thermalisation of the trapped photon gas. Commercial Opportunity: For many Laser applications, coherent but not necessarily monochromatic light is required. The strong light concentration effect of BEL and the generation of coherent light with high intensity offer opportunities for a range of applications. For these applications, BEL can be a efficient light source for coherent visible and UV light. In contrast to a Laser, where significant share of the energy is lost in heat, BEL allows the design of an efficient solid state “cold Laser”.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
