Editorial: Physical Review A, 75, p.061401, 2007.

Rezumat:

It is demonstrated that three-dimensional propagation effects essentially influence attosecond-pulse generation by few-cycle, carrier-envelope-phase stabilized laser pulses used in a polarization-gating configuration.
The rapidly changing polarization status gives rise to electron trajectories even longer than those observed with
linearly polarized light, but the off-axis contributions and the propagation effects can efficiently act as a filter to produce a single attosecond pulse. It is also found that the attosecond beams can have a significant spatial
divergence.
