Abstract: The destruction of the spatial coherence of multimode laser radiation in a delay-line-based system is analysed theoretically and experimentally. A scheme of a coherence-transforming device operating in a broad wavelength range and various lasing regimes is proposed. This scheme is shown to be efficient for rapid speckle-noise suppression in optical recording and lithography.
