| Abstract: | A new polarization gating is demonstrated by our principle-of-proof experiment,which is theoretically proposed to generate the isolated or double attosecond pulses with the multi-cycle driving laser pulse in the previous workOptics Express.20,5196(2012)].In the experiment,the polarization gating is formed by two orthogonally-polarized linearly chirped multi-cycle laser pulses,and the spectral bandwidths of the harmonics are broadened by more than two times,which agree with the previous theoretical work. |
