Diode-laser-pumped monolithic nonplanar ring oscillators (NPRO's) in an applied magnetic field can operate as unidirectional traveling-wave lasers. The diode laser pumping, monolithic construction, and unidirectional oscillation lead to narrow linewidth radiation. In this paper, the authors present a comprehensive theory of the eigenpolarizations of a monolithic NPRO. The authors explain how the properties of the integral optical diode that forces unidirectional operation depend on the choice of the gain medium, the applied magnetic field, the output coupler, and the geometry of the nonplanar ring light path. Using optical equivalence theorems to gain insight into the polarization characteristics of the NPRO, the authors offer a strategy for designing NPRO's with low thresholds and large loss nonreciprocities. The authors present an analysis of the eigenpolarizations for one such NPRO, consider alternative optimization approaches, and discuss briefly the prospects for further reducing the linewidths of these lasers.
