摘要：
Interference effects arising during the highly nonlinear interaction of intense laser pulses with matter are presented for applications in attosecond spectroscopy and interferometry. In the first part we theoretically describe an approach to excite and measure bound electron wavepackets where temporal interference in the photoelectron momentum spectrum reveals the complete energy-level structure of an atom. In the second part we analyse and discuss experimentally observed interference patterns of few adjacent attosecond pulses generated in neon gas that can be controlled by varying experimental parameters such as carrier-envelope phase (CEP) or pressure.
