In the preceeding study, fractal speckles with higher intensities were realized by generating bright power-law intensities by means of a phase-only SLM, on which a CGH calculated from the iterative Fourier transform algorithm is displayed. However, the produced power-law intensities have significant random features due to the initial random phase in the iteration. In the present paper, we derive a CGH to produce the power-law intensity profile theoretically on the basis of the method of stationary phase to supress such significant random noise.
