چکیده
Time domain Ramsey-type interferometry is useful for investigating spectroscopic information of quantum states in atoms and molecules. The energy range the to be observed with this scheme has now reached more than 20 eV by resolving interference fringes a period few hundred attoseconds. This attosecond requires irradiation coherent pair extreme ultraviolet (XUV) light pulses, while all methods used deliver XUV pulse until have relied on division source an two before generation. In paper, we report novel technique perform splitting high-order harmonic (HH) sub-20 fs laser after its By virtue postgeneration HH pulse, demonstrated that optical emerging at complete temporal overlap seamlessly continued electronic helium atom. applicable studying femtosecond dephasing dynamics wavepackets exploring ultrafast evolution cationic system entangled ionized electron resolution.

15 صفحه اولAttosecond pulse walk-off in high-order harmonic generation.
We study the influence of the generation conditions on the group delay of attosecond pulses in high-order harmonic generation in gases. The group delay relative to the fundamental field is found to decrease with increasing gas pressure in the generation cell, reflecting a temporal walk-off due to the dispersive properties of the nonlinear medium. This effect is well reproduced using an on-axis ...
متن کاملSingle attosecond pulse generation in the multicycle-driver regime by adding a weak second-harmonic field.
We present a method of producing single attosecond pulses by high-harmonic generation with multicycle driver laser pulses. This can be achieved by tailoring the driving pulse so that attosecond pulses are produced only every full cycle of the oscillating laser field rather than every half-cycle. It is shown by classical and quantum-mechanical model calculations that even a minor addition (1%) o...
