Scientists have 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.
