In this work we present results of a GPU-accelerated wave-optical model for external-cavity diode lasers containing a beam transformation system to symmetrize the beam qualities in fast and slow axis. We show the rotation of the beam profile and analyze the feedback field into the diode. We further consider the effect of misaligned optical elements on the feedback field.
