Abstract
Occurs with coherent sources when, for a variety of reasons, the parabasal rays begin to diverge and are no longer linear. The error is triggered whenever any invariant exceeds a prescribed value (0.1 waves is the default). Normally, if parabasal rays remain in a linear region about the base ray, several orthogonal invariants should be equal to zero.

Solution
Confirm that each Gaussian beam samples a small sufficient area of an optical element to remain locally quadratic to within an acceptable level of accuracy. You may need to DECOMPOSE the field earlier into a new set of Gaussian beams.
