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…

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…
