The modes of an unstable aligned empty strip resonator are found using the kernel expansion technique with the linear prolate functions as a basis set. Calculations of the modes are used to examine the accuracy of the asymptotic methods at low equivalent Fresnel numbers and to demonstrate the orthogonality of the cavity modes.
