Attosecond Control of Ionization by Wave-Packet Interference
Attosecond Control of Ionization by Wave-Packet Interference
A train of attosecond pulses, synchronized to an infrared (IR) laser field, is used to create a series of electron wave packets (EWPs) that are below the ionization threshold in .helium. The ionization probability is found to strongly oscillate with the delay between the IR and attosecond fields twice per …
