Russians and Indians made ​​perfected laser

The team of scientists from Vicksburg University in Germany has developed a new laser polaritonik. This work involved Russian - Vladimir Kulakovski from Institute of Solid State Physics.Improved laser does not use electrons, but polaritons. These are integral parts of the particle with the energy that makes the electromagnetic part, and in part - the energy of the excited state of the environment. The most common laser electron is in a high state - otherwise radiation emissions will not start. New laser could not function without this condition.Another advantage polaritonika is much faster start and stop. The signals from this device can be much more, or much less energy transmitted through the optical cable lines.Another advantage of the new generation of lasers is that, they will complement radiography. In addition, they are much safer imaging.Polaritonici are able to work in a very promising terahertz frequencies, which are increasingly popular in the world. In Japan terahertz frequencies used for wireless networks.Interestingly, in parallel with the Russian-German scientific team engaged in the elaboration of a team of experts from the University of Michigan USA. At its head is a professor from India Palab Bhatahara. Both projects are independently came to the same results.
