Presented in this paper is the technique of formation of required laser intensity distribution on the target with a reduced speckle noise. The method is based on the use of modified Fourier hologram adapted to controlled phase modulators. Reduction of the speckle noise in the laser energy profile is obtained using multiple incoherent superposition of synthesized holographic images. Each hologram is synthesized with different random diffuser. The advantages of this method: relative simplicity of hardware; robustness with regard to distortions of any kind in input beam and/or optical path of the scheme; controlled reduction of the speckle noise in the final energy distribution.
