The Pound–Drever–Hall (PDH) technique is a widely used and powerful approach for stabilizing the frequency of light emitted by a laser by means of locking to a stable cavity. The PDH technique has a broad range of applications including interferometric gravitational wave detectors, atomic physics, and time … Prikaži več In recent years the Pound–Drever–Hall technique has become a mainstay of laser frequency stabilization. Frequency stabilization is needed for high precision because all lasers demonstrate frequency wander at some … Prikaži več Phase modulated light, consisting of a carrier frequency and two side bands, is directed onto a two-mirror cavity. Light reflected off the … Prikaži več Prominently, the field of interferometric gravitational wave detection depends critically on enhanced sensitivity afforded by optical cavities. The PDH technique is also used when … Prikaži več The PDH readout function gives a measure of the resonance condition of a cavity. By taking the derivative of the cavity Prikaži več Splet29. jul. 2015 · PhD Thesis - In the present thesis, we studied necrotic pulps associated or not with apical periodontitis and the efficacy of intracanal medication.
