Abstract
- Interferometry, as the key technique in modern precision measurements, has been used for length diagnosis in the fields of engineering metrology and astronomy. Analogous interferometric technique for time domain precision measurement is a significant complement to the spatial domain applications and requires the manipulation of the interference on the extreme time and energy scale. Here we present an all-optical interferometry for high precision measurement with attosecond temporal and hundreds of meV energy resolution. The interferometer is based on laser driven high order harmonics which provide a robust sequence of attosecond temporal slits. As applications, we reconstruct the waveform of an arbitrarily polarized optical pulse using the time resolving capability, and capture the abnormal character of the transition dipole near a Cooper minimum in argon using the energy resolution provided. This novel attosecond interferometry opens the possibility for high precision measurement in time energy domain using an all-optical approach.<br />Comment: 12 pages, 5 figures in main text and 9 pages, 7 figures in supplementary material
