Abstract

Abstract : A new calibration method for dual‐mask liquid crystal spatial light modulators (SLMs) is presented, which can be applied while the SLM is in the setup of a pulse shaper optimised for semiconductor laser sources. An evolutionary algorithm is used to retrieve the phase retardances from the transmitted spectral intensity.
