Towards intense single-digit attosecond pulses with a 100-mJ-class mid-infrared sub-cycle laser
Kaito Nishimiya, Rambabu Rajpoot, Eiji J Takahashi
The duration of isolated attosecond pulses created via high-order harmonic generation is determined by the number of optical cycles in the driving laser. Achieving shorter attoseco…

Advances in dual-chirped optical parametric amplification
Kaito Nishimiya, Eiji J. Takahashi
High-energy infrared lasers have enabled the generation of strong field phenomena, and among such phenomena, high-order harmonic generation (HHG) from gases has enabled attosecond-…

Perturbed three-channel waveform synthesizer for efficient isolated attosecond pulse generation and characterization
Dianhong Dong, Hushan Wang, Bing Xue +5
The generation of gigawatt-class isolated attosecond pulses (IAPs) is vital for attosecond pump-probe experiments. In such experiments, the temporal duration of IAPs must be determ…
