Modal patterns for the three Porro angles with increasing effective Fresnel number to the right in each row. As NF is increased (through an increase in aperture size), the modes become more complex, departing from the petal-like standard. The authors apply a new method of modeling Porro prism resonators, using the concept of rotating loss screens, to study stable and unstable Porro prism resonator. [See - L. Burger and A. Forbes Fig. 3 for details.]
