SASE X-Ray Free Electron Laser in DESY --The 4th Generation Light Source

The SASE - Free Electron Laser, the new light source constructed at DESY in Hamburg will sharpen the sight of 21st century scientists to an extent that has never been reached before. they allow contrasty pictures of atomic structures to be taken in a way which is not possible today. A laser for X-ray radiation will open up new insights into the depths of living cells, molecules, and materials. It is an ultra-brilliant X-regime light (XFEL), a 300 meter long Free Electron Laser without mirrors and laser seed, the world-wide first and only X-ray laser of this kind.
