"mode" in inglés with examples - Collocation dictionary inglés
- One of the biggest hurdles for implementation of the NICE-OHMS technique is indisputably the locking of the frequency of the laser to that of a cavity mode.
- Without an etalon, a laser will generally produce light over a wavelength range corresponding to a number of cavity modes, which are similar to Fabry-Pérot modes.
- Inserting an etalon into the laser cavity, with well-chosen finesse and free-spectral range, can suppress all cavity modes except for one, thus changing the operation of the laser from multi-mode to single-mode.
- The last term models coupling between the cavity mode and a classical field, i.e. a laser.
- Single-mode lasers employ etalons to suppress all optical cavity modes except the single one of interest.
- For excessive net group delay dispersion (GDD) of the laser cavity, the phase of the cavity modes can not be locked over a large bandwidth, and it will be difficult to obtain very short pulses.
- When the RF frequency fed by the antenna is the same as that of a cavity mode, the resonant fields build to high amplitudes.
- When the laser is in resonance with a cavity mode, intensity builds up in the cavity due to constructive interference.
- However, for high finesse cavities the ratio of "on" and "off" a cavity mode is small, given by the inverse of the finesse, whereby the transmission as well as the integrated absorption becomes small.
- This formulation requires one equation for the carrier density, and one equation for the photon density in each of the optical cavity modes:
