We have developed a beam stabilization system for high-power femtosecond lasers operating at a repetition rate of 1 kHz. The beam pointing at a hollow fiber input was stabilized to within 1 μm rms and the fluctuations of the broadened spectra and power were significantly improved. This technique enables us to increase the input power to a hollow fiber for intense few-cycle pulse generation.
