The shortest laser pulses generated in the visible spectral region today consist of less than two optical cycles in full-with half-maximum of the pulse's envelope. Depending on the phase ("absolute phase") of the carrier frequency with respect to the envelope, the electric field of such pulses changes, see figure 1. This new quantity for the characterization of a laser pulse has important consequences for a many non-linear processes in many disciplines, in particular sub-femtosecond and attosecond physics.
