Abstract

A multispectral wavefront sensor can be used to perform a single-shot spatio-temporal characterization of a laser pulse. In order to measure the spatio-spectral electric field, a laser pulse can be spectrally modulated, separated and measured by a wavefront sensor. In order to simplify the experimental setup and hardware control, the single wavefront sensor can be used. In this research we discuss the development of the multi-channel wide-aperture high-resolution Shack-Hartmann sensor for multispectral wavefront sensing. The whole sensor area of 15×15 mm was divided into four logical apertures, each for separate laser beam. The development and calibration procedure are described. The wavefront sensor control software is developed and tested.
