Free electron lasers (FELs) are powerful sources for efficient XUV generation. They deliver very intense femtosecond pulses in the XUV and X-ray regime, which can be used for a wide range of experiments from material science to time resolved atomic physics. Presently, XUV and X-ray FELs start lasing from an electron bunch in an undulator by means of spontaneous emission of synchrotron radiation (SASE). At the FEL facility FLASH (Free electron LASer at Hamburg) it is planned to seed an FEL for the first time in a wavelength range below 40 nm with a laser driven higher harmonics generation (HHG) source. We present the seeding concept and characterization measurements for the newly developed HHG source. Further we will motivate, how future time resolved ultrashort experiments will benefit from seeded FELs.
