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…
High-harmonic generation in liquids with few-cycle pulses: effect of laser-pulse duration on the cut-off energy
Angana Mondal, Benedikt Waser, Tadas Balciunas +5
High-harmonic generation (HHG) in liquids is opening new opportunities for attosecond light sources and attosecond time-resolved studies of dynamics in the liquid phase. In gas-pha…
Time-resolving magnetic scattering on rare-earth ferrimagnets with a bright soft-X-ray high-harmonic source
G. Fan, K. Legare, V. Cardin +16
We demonstrate the first time-resolved X-ray resonant magnetic scattering (tr-XRMS) experiment at the N edge of Tb at 155 eV performed using a tabletop high-brightness high-harmoni…
Bismuth Ferrite Dielectric Nanoparticles Excited at Telecom Wavelengths as Multicolor Sources by Second, Third, and Fourth Harmonic Generation
Jeremy Riporto, Alexis Demierre, Cédric Schmidt +9
We demonstrate the simultaneous generation of second, third, and fourth harmonic from a single dielectric Bismuth Ferrite nanoparticle excited by a telecom fiber laser at 1560 nm.…
