Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm
Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot. In particular, a two-dimensional phase pattern is retrieved and de
