Carrier Envelope Offset
The offset between the optical phase and the maximum of the Wave envelope of an optical pulse.
The time dependence of the electric field associated with an optical pulse can be described as a fast sinusoidal oscillation, called the carrier, multiplied by a more slowly varying envelope function. When the pulse propagates through a medium, the relative position between the carrier wave and envelope will in general change due to chromatic dispersion, causing a difference between Phase Velocity and group velocity, and possibly also due to optical nonlinearities. The carrier–envelope offset phase of a pulse is defined as the difference between the phase of the carrier wave and the envelope position, the latter being converted to a phase value.
