Techniques Converge, Yield Attosecond Spectroscopy Milestone
BERLIN, March 5, 2024 — Researchers at the Max Born Institute in Berlin have demonstrated attosecond-pump attosecond-probe spectroscopy (APAPS) at a repetition rate of 1 kHz. The advance opens new avenues for the investigation of extremely fast electron dynamics in the attosecond regime. Current pump-probe setups for the investigation of attosecond phenomena typically pair a weak extreme ultraviolet (XUV) pulse generated through high harmonic generation with intense NIR pulses in the femtosecond range, with each
