    "abstract": "Since spring, 2005 vacuum ultraviolet free electron laser (VUV FEL) at DESY\noperates as user facility in the wavelength range around 30 nm. Electron beam\nformation system at the VUV FEL is essentially nonlinear and naturally results\nin a formation of a short high-current leading peak in the density distribution\nthat produces FEL radiation. The main feature of the femtosecond mode of\noperation of the VUV FEL is the production of short, down to 20 fs radiation\npulses with GW-level peak power. This paper is devoted to detailed studies of\nthe short-pulse effects in the VUV FEL at DESY operating in the femtosecond\nregime, and to analysis of first experimental results.",
