A collaborative research team from Nanjing University of Science and Technology (NJUST) and East China Normal University (ECNU) has theoretically proposed that a pump-probe high-harmonic spectroscopy ...

Fig. 1: Experimental setup for attosecond-pump attosecond-probe spectroscopy. NIR pulses are focused behind a pulsed gas jet, where attosecond pulses are generated. At some distance from the gas jet, ...

A team of researchers from the Max Born Institute (MBI), in Berlin, Germany, has for the first time demonstrated attosecond-pump attosecond-probe spectroscopy (APAPS) at a repetition rate of 1 ...

Nonlinear optics is the branch of photonics that studies material responses wherein the induced polarisation is not directly proportional to the applied electromagnetic field. In these media, intense ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
