Abstract

This paper describes a wave optics end-to-end laser beam train model and applies it to an outgoing wavefront sensor (OWS) adaptive optical system. The model permits evaluation of complete beam trains by passing a complex field through each optical element as it occurs in the real beam train. The model has been used to evaluate the effects of the OWS imaging the primary mirror instead of the deformable mirror (DM). The results show that the imperfect imaging of the DM by the OWS that occurs as a result of the finite propagation distance from the DM to the OWS can influence the beam quality depending on spatial frequency content of the wavefront, propagation distance, and actuator spacing.
