S M Loktev, N M Lyndin, O Parriaux, V A Sychugov and A V Tishchenko, “Reflection of a finite light beam from a finite waveguide grating”, Quantum Electron. **27**, 445-449 (1997). [https://doi.org/10.1070/qe1997v027n05abeh000959](https://doi.org/10.1070/qe1997v027n05abeh000959)

Real beams are finite and so are real gratings. This paper gives a method for the diffraction of a finite Gaussian beam by a finite waveguide grating, shows that such a grating can serve as a mirror in a plane-parallel cavity, and demonstrates a waveguide mirror in a dye microlaser.

The resonance pole parameters this analysis rests on are what the Analysis dialog of the four one-dimensional codes computes for a finite Gaussian beam; the product page cites it for exactly that.
