Bright Coherent Ultrahigh Harmonics in the keV X-Ray Regime from Mid-Infrared Femtosecond Lasers
Tenio Popmintchev, Ming-Chang Chen, Dimitar Popmintchev +17
High harmonic generation traditionally combines ~100 near-infrared laser photons, to generate bright, phase matched, extreme ultraviolet beams when the emission from many atoms add…
Central frequency of few-cycle laser pulses in strong-field processes
Joel Venzke, Tennesse Joyce, Zetong Xue +2
We analyze the role of the difference between the central frequencies of the spectral distributions of the vector potential and the electric field of a short laser pulse. The frequ…
Generation of Bright Isolated Attosecond Soft X-Ray Pulses Driven by Multi-Cycle Mid-Infrared Lasers
M. -C. Chen, C. Hernández-García, C. Mancuso +11
High harmonic generation driven by femtosecond lasers makes it possible to capture the fastest dynamics in molecules and materials. However, to date the shortest attosecond (as) pu…
