Frequency-Controlled Isolated Attosecond Pulses Characterized by Both 750 and 400 nm Wavelength Streak Fields

摘要

Frequency tunability of isolated attosecond pulses provides options for the study of temporal dynamics and phases of electronic processes [1]. Techniques to generate frequency-controlled attosecond pulses (XUV and VUV) and wavelength selective streak pulses (NIR and UV) are discussed here. A novel Mach-Zehnder (MZ) interferometer is used to combine all optical fields before the high-harmonic generation region.
