Proposal of carrier-envelope-phase stable attosecond pulse generation based on laser-plasma electron source

摘要

Summary form only given. Ultrafast electron dynamics determines how physical and chemical changes occur at a fundamental level. The investigation of such processes requires (isolated) attosecond pulses [1]. On all time scales down to the attosecond regime, there are a number of physical processes that depend on the electric field, rather than just the intensity envelope of a driving pulse. There have been numerous proposals to produce ultrashort pulses in free-electron lasers (FELs) [2]. However, the temporal coherence of the output radiation is limited. In order to solve this problem, we proposed a robust method for producing waveform-controlled CEP-stable attosecond pulses in the EUV spectral range in a FEL [3]. Here, we investigate the feasibility of our setup when a laser-plasma accelerator (LPA) is used as the electron source, rather than a LINAC.
