Roadmap on Attosecond Science
Rocio Borrego Varillas, Pierre Agostini, Fernando Ardana-Lamas +108
Twenty-five years have passed since the first experimental demonstration of attosecond pulses, marking the advent of our ability to resolve and control electron motion in real time…
Time-domain measurement of Auger electron dynamics in xenon atoms after giant resonant photoionization
Mahmudul Hasan, Jingsong Gao, Hao Liang +7
Time-resolved measurement of Auger-Meitner (AM) decay [Nature 419, 803 (2002)] marked a milestone in the development of attosecond science. To date, the time constants for the AM d…
Strong-Field Photoelectron Interferometry with Near-Single-Cycle Yb Lasers
Mahmudul Hasan, Phi-Hung Tran, Jingsong Gao +8
The concept of using photoelectron interferometry in short laser fields to probe electron dynamics and target structures was introduced more than two decades ago. However, the qual…
Bright 25-attosecond light pulses reach the one atomic unit of time
Jingsong Gao, Mahmudul Hasan, Hao Liang +8
Generating ever-shorter and brighter light pulses has long been a central pursuit in ultrafast science, as it benchmarks our ability to create and manipulate the coherence on the i…
Hearing carrier-envelope offset frequency and phase in air with a microphone
Meng Han, Ming-Chang Chen, Ming-Shian Tsai +1
Attosecond science and frequency metrology rely on the precise measurement and control of the laser pulse waveform, a feat traditionally achieved using optoelectronic techniques. I…
Filamentation-Assisted Isolated Attosecond Pulse Generation
Yu-En Chien, Marina Fernández-Galán, Ming-Shian Tsai +6
Isolated attosecond pulses (IAPs) generated by few-cycle femtosecond lasers are essential for capturing ultrafast dynamics in atoms, molecules, and solids. Nonetheless, the advance…
