A team at the Laboratory for Attosecond Physics (LAP) in Garching (Germany) has constructed a detector, which provides a detailed picture of the waveforms of femtosecond laser pulses (1 fs = 10-15 seconds). Knowledge of the exact waveform of these pulses enables scientists to reproducibly generate light flashes that are a thousand times shorter – lasting only for attoseconds – and can be used to study ultrafast processes at the molecular and atomic levels.

Modern mode-locked lasers are capable of producing extremely short light flashes that last for only a few femtoseconds. In one femtosecond light, which rushes from the Earth to the Moon in just one second, advances only three ten-thousandths of a millimeter. Such short pulses consist of only one or ...
