Abstract:

This report summarizes accomplishments pertaining to two new methods for analyzing unstable resonators a a waveguide method, and b a ray-optical method. The waveguide method has been found effective for calculating eigenvalues, but not eigenmodes, in symmetric configurations with sharp-edged or round-edged mirrors, and with misaligned mirrors. The ray-optical method has been found effective not only for these same configurations but also for nonsymmetric structures containing internal axicons. Moreover, it yields the eigenvalues as well as the eigenmode fields. Therefore, the ray method promises to provide a useful tool for studying features introduced by successive complication of the resonator model. Author
