Near single-cycle pulse generation using a cascaded all-bulk multi-pass cell compression system
Saga Westerberg, Gaspard Beaufort, Sara Rushe Palacios +5
We experimentally demonstrate the generation of sub-two-cycle optical pulses using a cascaded post-compression scheme based on two bulk multi-pass cells. Starting from 220 fs, 100…

Enhanced dynamic range spatio-spectral metrology of few-cycle laser pulses
Cristian Alexe, Aaron Liberman, Saga Westerberg +13
Accurate spatio-temporal and spatio-spectral metrology is critical to the characterization and use of ultra-short, high-power lasers. The emergence of few cycle pulses, with bandwi…
