摘要：

Using a laser pulse along with a helium gas jet, high-order harmonics were obtained from different quantum paths by controlling the phase-matching condition. High-order harmonics were selected from a single path. An attosecond pulse train was generated with a single attosecond pulse per half-optical cycle, adding harmonics. Short pulses formation was possible using a large number of harmonics.
