Schematic of the experimental setup.
A wedge disperses the pulse prior to the focusing mirror, leading to wavefront rotation. The attosecond pulses generated in each half-cycle of the laser pulse propagate in different directions. A slit selects one attosecond pulse from the spatially separated train. The spectrum of the selected isolated attosecond pulse is measured with the MCP detector. A weak SHG beam is incident at small angle with respect to the fundamental beam. The insert shows the temporal electric-field of the laser pulse at the focus.
