Abstract
A single-pass free electron laser (FEL) based on the principle of self-ampl ified spontaneous emission (SASE) is currently under test at the TESLA Test Facility at DESY. So far lasing has been observed in the vacuum ultraviole t (VUV) region between 80 and 180 nm. The photon beam has been characterize d by different techniques in order to provide experimental evidence for SAS E and to compare with numerical simulations. This paper presents some of th e first results and summarizes the techniques used for the measurement of t he photon beam intensity, its angular and spectral distribution, and its st atistical properties.
