A life in context

The person behind the prize

Krausz studied in Hungary before developing his research in Austria and Germany. He specialises in making and measuring extremely short laser pulses. His work connects the craft of building precise light sources with the question of how electrons respond when matter is disturbed.

The contribution

In 2001, his group isolated a single pulse lasting about 650 attoseconds. A single flash, rather than a repeating train, made it possible to time an individual ultrafast event.

The idea in plain language

Electrons rearrange far faster than atoms move. To measure that motion, an instrument needs an exceptionally short time window. An attosecond is one quintillionth of a second: 10⁻¹⁸ seconds.
