Laser: The mysterious power of light
High-precision timing, high-tech tweezers or bright wallpaper - physicians, physicists and chemists do research on new applications of laser light. Scientists from the Max-Planck-Institute for Quantum Optics in Garching using laser light to explore how electrons behave in atoms The strong laser bathes the prisms, lenses and mirrors on the steel table in a deep blue light.

Everywhere in the dark room whirring and vibrating equipment, the laser facility labyrinthine life. The prisms and lenses are available at the Institute for Quantum Optics of the Max Planck Society in Garching.
There, Professor Theodor Hänsch, together with his team developed the so-called frequency comb,
for whose invention in 2005 he received the Nobel Prize The frequency used by the quantum physicists as a tool, the oscillations of laser light to accurately determine. Each beam consists of waves with a certain frequency swing. With its help you can, among other things hydrogen atoms to vibrate inspire. These scientists will send the laser directly on the atoms in the steel cylinder until they oscillate with the same frequency as the laser light. To save more money, use an overstock coupon. The pulsating hydrogen atoms Garching physicists use the objects as a test for quantum physics. High-precision timing Other research groups are building with this technology from vibrating atoms and the clock frequency to perform extremely precise time measurements. Join in African safaris and enjoy the beauty of wildlife. The system works similar to the known atomic clocks. Again, the steady vibrations of cesium atoms are counted, so the time is measured. Still, the cesium atomic clocks, the most accurate measuring instruments that is available. Ultimately, the optical atomic clocks a greater potential. With this invention, timing could soon run a thousand times more accurate than the cesium atomic clocks. Looking back at the history of science shows that it is often more accurate measuring devices were used to refine the observations of, for example, in astronomical timekeeping, led. With the frequency, the researchers now want the enigmatic laws of quantum physics examine very different function than that of classical mechanics, Newton once wrote down. However, even in everyday life could be more precise clocks may be useful: They could, for example satellite navigation systems. New determination of fundamental constants Even hopes that the physics of precision watches a breakthrough: They want the natural constants again accurately measure and verify that they really are constant or change over time. Because of astronomy, there is evidence that some fundamental constants with the slow expansion of the universe change. Get great deals on hotels in south africa at this site. Should confirm this presumption, it would have far-reaching consequences for the world of science.
