"These high-power attosecond X-ray pulses could open new avenues for studying ... Terawatt-attosecond hard X-ray free-electron laser at high repetition rate, Nature Photonics (2024).

A new gating scheme based on polarization control and second-harmonic generation is greatly simplifying the production of isolated attosecond pulses. Attosecond pulses — flashes of light lasting ...

pulses in the X-ray spectrum using high-harmonic generation. Attosecond laser sources are now poised to become the next tool for probing dynamic chemical processes with unprecedented time resolution.

New work solidifies UConn's position as a world-class laser research institution University of Connecticut professor of physics ...

Ordinary laser systems cannot generate anything shorter than a ... When the peaks in the frequency coincide, this increases the intensity of the light creating a train of attosecond pulses. This is ...

Strong driving pulse E0 generates high order harmonics every half optical cycle of the driver, and forms a sequence of attoecond temporal slits. A weak signal pulse perturbs the electron ...
