Investigation of the Newly Proposed Carrier-Envelope-Phase Stable Attosecond Pulse Source
Z. Tibai, Gy. Tóth, Zs. Nagy-Csiha +3
Practical aspects of the robust method we recently proposed for producing few-cycle attosecond pulses with arbitrary waveform in the extreme ultraviolet spectral range are studied…
