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.

The basic idea is that the cavity length can be measured by the laser frequency and vice versa. This creates an error signal around the resonance of the cavity, which is proportional to the deviations in the length.
