Pump-probe experiments are widely used to understand the dynamics of materials on the timescale of electronic, atomic and molecular motion before damage process occurs. While nowadays the required femtosecond x-rays used as probe pulses are mostly...2019-08-26
A crucial parameter of ultrashort high peak power laser systems is the temporal contrast ratio, which is defined as the intensity ratio of the main pulse to the background noise. A poor contrast ratio indicates strong pre-pulses or a pedestal befo...2019-08-26
The peak power of ultrashort laser systems has grown dramatically in the range of 1021–1022 W/cm2 owing to the rapid development in the chirped pulse amplification (CPA) and optical parametric CPA (OPCPA) techniques. Such an intense laser provide...2019-08-26
The radiation from accelerated particles and the consequent radiation-reaction (RR) effect is one of the oldest and most fundamental problems in electrodynamics, where particles lose momentum from radiation. For most problems, one can calculate th...2019-08-21
Spin-polarized particle beams are widely used in modern physics including nuclear physics, particle physics as well as material science. In particular, polarized electron beam plays an important role in electron-positron colliders, which enhances ...2019-08-19
The electromagnetic interference (EMI) shielding window is of great significance for precision aeronautic, medical, civilian, and research facilities. There are tremendous world-wide efforts in searching new structures and materials with excellent...2019-08-21
