Optical cavity stability

Weboptical cavity. Optical radiation circulates within the cavity, bouncing back and forth between the end mirrors and passing through the gain element. Resonators can be stable or unstable. Stability is determined by the radii of curvature of the mirrors, the spacing between the mirrors, and the refractive index of WebDec 16, 2011 · Download PDF Abstract: State-of-the-art optical oscillators based on lasers frequency stabilized to high finesse optical cavities are limited by thermal noise that causes fluctuations of the cavity length. Thermal noise represents a fundamental limit to the stability of an optical interferometer and plays a key role in modern optical metrology.
