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

The Private Line Automatic Ringdown for Trading Turrets feature improves connection service for turrets in the financial industry—primarily for corporations and enterprises that use turrets and POTS telephones for trading. Implementation of this feature ensures that a call between traders on a private line automatic ringdown (PLAR) connection

This report is a guide to the use of the Sandia-developed Ringdown extraction from current ringdown waveforms and describes how to use the tool to.

Ringdown circuits are used when you want a telephone to dial a certain number immediately upon lifting the handset or pressing a button. An emergency phone on the street might use a ringdown circuit. It may even use a dedicated line that goes directly to a dispatcher. An elevator phone is another example.

The Viking® DLE-200B™ Emergency Telephone Ringdown Circuit produces two-way communication between analog telecom devices by simulating an analog phone line.

A complete conda environment that includes all the prerequisites (and more!) to install ringdown can be found in environment.yml in the current directory: conda env create -f environment.yml

We report a proof-of-principle demonstration of intracavity pump–probe, cavity ringdown (CRD) detection in a three-mirror, traveling-wave cavity.

2001/4/30 · Over the past decade, cavity ringdown spectroscopy has emerged as a powerful technique for performing direct absorption measurements using pulsed lasers. Developed in 1988, cavity ringdown spectroscopy has since been used from the ultraviolet to the mid-infrared. 1 In a typical ringdown experiment, a short laser pulse is injected into a cavity

ringdown ( plural ringdowns ) ( astronomy) The stage in a black hole merging event where the gravitational wave amplitude reaches its peak. ( telecommunications) A signal to a telephone operator that both rings a bell and allows a relay to drop.
