Attosecond Electron Sheets and Attosecond Light Pulses from Relativistic Laser Wakefields in Underdense Plasmas

摘要

A method for producing dense attosecond electron sheets (tens nanometers thick corresponding to attosecond duration) and single intense attosecond light pulse is reported based on relativistic laser wakefields in underdense plasmas. By making use of gas targets this method allows for high repetition rates required for applications.
