Max Born Institute attosecond imaging development

Overview

Researchers at the Max Born Institute have developed a laboratory-based technique called “all-attosecond transient-absorption spectroscopy” to observe electronic dynamics.

By using attosecond light pulses for both excitation and probing, the method allows scientists to resolve the oscillating motion of an electron hole in xenon ions with a period of approximately three femtoseconds. This approach utilizes extreme ultraviolet pulses to minimize perturbations to the system, avoiding the interference often caused by combining ultraviolet pulses with intense near-infrared pulses. The findings, published in Nature Communications, provide a clearer view of ultrafast electronic processes that drive phenomena such as chemical reactions and charge transport in solids.
