A "femtoslicing" facility to generate ultrashort x-ray pulses by laser-electron interaction [1] is being commissioned at the BESSY II storage ring. The energy modulation of electrons by femtosecond laser pulses of several mJ in an undulator is a good test case for FEL seeding schemes. The dependence of the interaction efficiency on various parameters is measured and compared to simulations and analytical results.
