Transparent Iron

When one thinks of iron one thinks of a dull grey solid. Transparent iron is an odd thought. The effect of electromagnetically induced transparency (EIT) is a known phenomena from laser physics. With intense laser light of a certain wavelength it is possible to make a non-transparent material transparent for light of another wavelength. This effect is generated by a complex interaction of light with the atomic electron shell. At DESY's X-ray source PETRA III, the Helmholtz research team of Röhlsberger managed to prove for the first time that this transparency effect also exists for X-ray light, when the X-rays are directed towards atomic nuclei of the Mössbauer isotope iron-57 (which makes up 2% of naturally occurring iron). The potential real world benefit for this phenomena may be in the a quantum effects computer which would be extremely fast.
