英文摘要We propose and demonstrate the adaptive conversion of input beam with unsymmetrical intensity distribution into a near-diffraction-limited flattop beam with desired parameters in the near field based on a combination of dual phase-only liquid crystal spatial light modulators (LC-SLMs) and the stochastic parallel gradient descent (SPGD) algorithm. One phase-only LC-SLM redistributes the intensity of the input beam to the desired distributions at the other phase-only LCSLM plane, and the other phase-only LC-SLM compensates the wavefront of the output beam. The SPGD algorithm adaptively optimizes the phase distributions of dual phase-only LC-SLMs to reduce the variance between the actual beam shape and the target beam shape. The experimental results on a prefabricated unsymmetrical input beam show that the technique is capable of adaptively creating near-diffraction-limited flattop beams with desired parameters. © 2016 SPIE.
