The Attoclock: A Novel Ultrafast Measurement Technique with Attosecond Time Resolution

The recent progress of the ultrafast laser technology enables to capture and control electrons dynamics, which is the key to understand how energy and charge are transported not only in atoms but also in more complex solid-state and molecular systems. This task calls for the development of novel measurement techniques with attosecond time resolution. The “attoclock” is a relatively simple method, which provides attosecond time resolution without the explicit need of attosecond pulses. In this chapter we review the details of this powerful experimental technique, which was employed in the recent years to investigate electron tunneling dynamics and to study the electron kinematics in strong field single and double ionization.
