Parallel to the enormous progress in optical and conventional X-ray lasers there have also been tremendous advances in the field of Free Electron Lasers (FELs) based on the principle of Self-Amplified Spontaneous Emission (SASE). At the TESLA Test Facility (TTF FEL) at DESY, a linac-driven SASE FEL has produced short pulses with GW peak power in the wavelengths range of 80-120 nm. The radiation pulse length has been adjusted between 30 fs and 200 fs. Currently an energy upgrade of the TTF linear accelerator to 1 GeV is being prepared which will make radiation wavelengths down to 6 nm available for users.
