The results of studies of a wavefront sensor based on the Talbot effect, in which a periodic grating made by laser printing is used, are presented. The optical characteristics of periodic gratings printed on polymer films exposed to a continuous radiation density of up to 0.9 W/cm2 have been studied. The possibility of creating efficient configurable wavefront sensors for lasers in the visible and mid-IR spectral ranges is demonstrated. Keywords: wavefront sensor, Talbot effect, wide-aperture laser beams, polymer films, periodic gratings.
