... decay strengths, the properties of the atom and resonator are significantly changed. For example, the cavity resonance is split into two peaks which are separated by the coupling constant between the atom and the resonator. Also, an excited atom emits its fluorescence photons mainly into the cavity. ...

... In the description of the gate mechanism given so far, the ion was treated as an ideal two-level system. Ac-Stark shifts are completely insignificant provided that the intensities of the blue- and the red-detuned frequency components are the same since in this case light shifts of the carrier transi ...

Mode-locking
Mode-locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s).The basis of the technique is to induce a fixed-phase relationship between the longitudinal modes of the laser's resonant cavity. The laser is then said to be 'phase-locked' or 'mode-locked'. Interference between these modes causes the laser light to be produced as a train of pulses. Depending on the properties of the laser, these pulses may be of extremely brief duration, as short as a few femtoseconds.
