We show that these oscillations arise from interplay among thermal expansion, the thermo-optic effect, and Kerr effects. In certain regimes we observe chaotic behavior and demonstrate that the threshold for this behavior can be predicted theoretically. We then demonstrate a self-stabilization technique that suppresses the oscillations and delivers high temperature and frequency stability without reference to external standards.en© 2015 American Physical SocietyJournal article003003116210.1103/PhysRevA.91.0638010003554087000052-s2.0-84930959762192061Weng, W.
