(PhysOrg.com) -- Subatomic events can be remarkably counterintuitive. Such is the case in theoretical physics when, under certain specific conditions, atoms exposed to intense infrared laser pulses remain stable rather than undergoing the ionization expected from electric fields at least as strong as the electrostatic forces binding the irradiated valence electrons. Inspired by the observed acceleration of neutral atoms1, and other recent experiments2, researchers at the Max-Born Institute for Nonlinear Optics in Berlin have shown that, in theory, angular resolved photoelectron spectroscopy can be used to directly image these so-called laser-dressed stable atoms.
A new class of high power lasers can effectively accelerate particles like electrons and ions with very intense, short laser pulses. Physicists have developed a new theoretical model for predicting the density and temperature of hot... Read Post
Researchers in Germany have succeeded in controlling and monitoring strongly accelerated electrons from nano-spheres with extremely short and intense laser pulses. When intense laser light interacts with electrons in nanoparticles t... Read Post
In 2009 researchers found an "ionization surprise" that defied explanation. Until that time, it had been commonly thought that the ionization of atoms by strong laser fields was well-understood, but novel experiments where rare gas ... Read Post
