Broadband cavity ringdown spectroscopy for sensitive and rapid

We demonstrate highly efficient cavity ringdown spectroscopy in which a broad-bandwidth optical frequency comb is coherently coupled to a high-finesse optical cavity that acts as the sample chamber. 125,000 optical comb components, each coupled into a specific longitudinal cavity mode, undergo ringdown decays when the cavity input is shut off.

What causes a black hole ringdown and why can it prove the no

1/8 · The ringdown is simply the black hole formed in the merger settling down to a final stationary form. According to the no-hair theorem, this stationary form has to be described by the Kerr family of metrics described by the mass and angular momentum of the final black hole (since the intitial system is assumed to be electrically neutral).

Ringdown - Emanuele Berti

Ringdown The oscillation modes of black holes are called "quasinormal modes" (QNMs; "quasi" because they are damped by the emission of gravitational radiation). These quantities are of interest in gravitational-wave astronomy, to test the so-called "no-hair theorem" of general relativity, and in the context of the gauge-gravity duality.

Cavity ring-down spectroscopy - Wikipedia

Cavity ring-down spectroscopy. Cavity ring-down spectroscopy ( CRDS) is a highly sensitive optical spectroscopic technique that enables measurement of absolute optical extinction by samples that scatter and absorb light. It has been widely used to study gaseous samples which absorb light at specific wavelengths, and in turn to determine mole
