Abstrakt: We present a diffractive phase variable attenuator for femtosecond laser radiation control. It allows the control of beam power up to 0.75.10(13) W/cm(2) without introducing serious distortions in spectra and beam shape while it operates in zero order diffraction. The attenuator can operate with wavelengths from DUV to IR.
