摘要：

High-harmonic emission is very sensitive to the polarization of a fundamental laser beam. By combining two short perpendicularly polarized pulses with frequencies centered at omega(1) and omega(2), where (omega(1)-omega(2))/omega(1) much less than 1, we can create a pulse with polarization that sweeps from circular through linear back to circular. It is possible to make the duration of the segment of the pulse capable of emitting short-wavelength radiation so small that emission is possible only for a time less than the period of the fundamental.
