Laser-Driven Nanoplasmas in Doped Helium Droplets: Local Ignition and Anisotropic Growth
Laser-Driven Nanoplasmas in Doped Helium Droplets: Local Ignition and Anisotropic Growth
Doping a helium nanodroplet with only a tiny xenon cluster of a few atoms sparks complete ionization of the droplet at laser intensities below the ionization threshold of helium atoms. As a result, the intrinsically inert and transparent droplet turns into a fast and strong absorber of infrared light. Microscopic …
