AB  - Typically, in self-Amplified spontaneous emission free electron laser (SASE FEL) based short-pulseschemes, pulse duration is limited by FEL coherence time. For hard x-ray FELs, coherence time is in a fewhundred attosecond range while for XUVand soft x-ray FELs it is in the femtosecond regime. In this paperthe modification of so-called chirp-taper scheme is developed that allows to overcome the coherence timebarrier. Numerical simulations for XUV and soft x-ray FEL user facility FLASH demonstrate that onecan generate a few hundred attosecond long pulses in the wavelength range 2–10 nm with peak powerreaching hundreds of megawatts. With several thousand pulses per second this can be a unique source forattosecond science.
