摘要：

We present a simple experimental apparatus, a time-of-flight mass spectrometer (TOFMS) and a photoelectron spectrometer (PES), for studying the ionization of molecules induced by intense femtosecond laser fields. Both the angular and the kinetic energy distributions of the ions and the photoelectrons can be precisely measured. As an example, the dynamics data for CS2 were measured using the spectrometer, and the results revealed that field-induced ionization played the main contribution for CS2 in an intense femtosecond laser field.
