Figure 1: The time variation of the electric field of laser pulses consisting of very few optical cycles depends on the phase Ï• of the carrier frequency with respect to the pulse's envelope.
Using a home-built time-of-flight mass spectrometer (TOFMS), a research team led by Prof. Haiyang Li from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has ...
