Autocorrelation Experiments with Soft X-ray FEL Pulses — R. Mitzner², W. Eberhardt¹, M. Neeb¹, T. Noll¹, M. Richter³, S. Roling², M. Rutkowski², B. Siemer², A. Sorokin³, K. Tiedtke⁴, and •H. Zacharias² — ¹BESSY GmbH, Albert-Einstein-Str. 15,12489 Berlin, Germany — ²Physikalisches Institut, Universität Münster, D-48149 Münster, Germany — ³PTB, Abbe_Str. 2-12,D-10587 Berlin, Germany — ⁴DESY, Nottkestr.85, 22603 Hamburg, Germany

We report first direct measurements of the average coherence time and temporal pulse length of soft X-ray fs pulses from the free-electron laser at DESY (FLASH) by means of linear and nonlinear autocorrelation.
