中文摘要：

A train of three equally spaced femtosecond laser pulses is employed to control the photoionization/photodissociation processes of cyclopentanone.With the increase of pulse separation,a strong modulation of product ion yield is observed.More than ten-fold changes of ion yield ratio between different products can be realized.The experimental observations further explain the compositions and formation pathways of peaks in the mass spectra.The controlling mechanisms are also discussed.
