Optical cavity stability

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. WebOct 27, 2024 · The open cavity is formed by the concave end facet of an optical fiber mirror and a planar mirror which also serves as a support for solid-state samples. The combined system allows locating the region of interest on the solid-state sample as well as in situ tuning of the cavity degrees of freedom.
