Anomalous photoelectron spectrum caused by finite interaction time in few-cycle xuv laser pulses
Yang Xiang, Yueping Niu, Yihong Qi +1
With the development of laser technology, pulse length enters the optical cycle regime and hence the interaction time between laser pulse and atoms becomes prominent. We investigat…

Sub-50 attosecond pulse generation from multicycle nonlinear chirped pulses
Yang Xiang, Yueping Niu, Yihong Qi +1
We present a method of producing single attosecond pulses by high-order harmonic generation with multi-cycle nonlinear chirped driver laser pulses. The symmetry of the laser feld i…

Control the high-order harmonics cutoff through the combination of chirped laser and static electric field
Yang Xiang, Yueping Niu, Shangqing Gong
The high harmonic generation from atoms in the combination of chirped laser pulse and static field is theoretically investigated. For the first time, we explore a further physical…
