Abstract
We demonstrate 2D random-addressing of a laser beam by computer-driven “Spatial Light Modulators” (SLMs), using ferroelectric liquid crystals (SSFLC effect). The beam scanning was obtained by placing SLMs inside the laser cavity. The “opened” pixels determine the configuration of the generating modes. The DPSSL (Nd:YAG) repetition rate is reported to operate in the kHz-range, scanning a field of 32*32 pixels. The optical schemes of dynamic correction for distortions in optical systems using optically-addressed LC SLMs are discussed. A diffraction efficiency up to 35% at the spatial frequency 50 pl/mm was obtained using the DHF effect. The images of non-coherent objects are obtained in a wide spectrum bandwidth (50-100 nm) using the lens with the real-time optically-addressed LC SLM holographic corrector. The near-DL resolution obtained at the lens optical distortions equivalent was found to be 0.006 rad.
