Fraunhofer ILT in Aachen has developed a highly complex laser-optical system for a quantum computer currently under construction at the 5th Institute of Physics at the University of Stuttgart. This ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

X-ray diffraction methods lie at the foundation of materials science. Determination of the crystal structures of natural minerals and, later, of crystals grown in the laboratory led to our ...

IF a fine beam of homogeneous cathode rays is sent nearly normally through a thin celluloid film (of the order 3 × 10 6 cm. thick) and then received on a photographic plate 10 cm. away and parallel to ...
