We present a novel approach to the accurate and rapid propagation of general 2D wavefronts via linear canonical transforms. An operator splitting approach divides both the crystal and the amplified laser pulse into slices, so that the algorithms remain 2D for an intrinsically 3D problem. The Synchrotron Radiation Workshop (SRW) code uses these matrices to transform the wavefront with physical optics. We are also developing a Python library for linear canonical transforms, which will enable wavefront propagation via more general ABCD matrices. Comparisons with experimental data are presented.
