The particular capabilities of selected combined adaptive optical systems for laser beam shaping in near infrared were studied. Fast switching sequences were obtained by combining an LCoS-SLM with angular-tuning, piezo-driven MEMS-axicons. By flexibly programming highly localized beams into SLM phase maps, the illumination of MEMS microaxicons, tunable spiral phase plates and Fresnel mirrors was optimized to enable for fast, variable and nondiffracting shaping performance. The approach can be applied to advanced types of optical processors like adaptive autocorrelators, or in micromachining. By varying the divergence of an illuminating beam with a liquid lens, spatio-temporal self-imaging of array patterns known as nondiffracting Talbot effect was demonstrated in adaptive mode with tunable Talbot distances.
