The Laser Interferometer Gravitational-Wave Observatory (LIGO) uses two 4-km Michelson–Fabry–Pérot interferometers for the detection of gravitational waves. [38] In this application, the Fabry–Pérot cavity is used to store photons for almost a millisecond while they bounce up and down between the mirrors.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. [1]
A more sensitive detector uses laser interferometry to measure gravitational-wave induced motion between separated 'free' masses. [7] This allows the masses to be separated by large distances (increasing the signal size); a further advantage is that it is sensitive to a wide range of frequencies (not just those near a resonance as is the case ...
The Laser Interferometer Space Antenna (LISA) is a planned space probe to detect and accurately measure gravitational waves [2] —tiny ripples in the fabric of spacetime—from astronomical sources. [3] LISA will be the first dedicated space-based gravitational-wave observatory.
The Free-orbit Experiment with Laser Interferometry X-Rays (FELIX) [1] belongs to a category of experiments exploring whether macroscopic systems can be in superposition states.
Laser resonators are often described as Fabry–Pérot resonators, although for many types of laser the reflectivity of one mirror is close to 100%, making it more similar to a Gires–Tournois interferometer. Semiconductor diode lasers sometimes use a true Fabry–Pérot geometry, due to the difficulty of coating the end facets of the chip.
