Abstract
The study of polarization evolution in a nonplanar, reentrant ring cavity is reported. In the numerical simulation, the factors which affect the polarization state within the cavity were considered. By measuring the polarization of a linear-cavity laser, we also derived the thermally induced optical axis rotation in the gain medium, and determined the equivalent themperature-dependent dielectric tensor of the gain medium at various pump powers, which enable Jones matrix analysis of the polarization in the nonplanar ring laser cavity. The laser cavity is compact and suitable for applications in cases in which unidirectional propagation is required. A highly stable single-frequency green laser was generated with an amplitude noise of less than 0.35%.
