the fastest time-resolution that is generated is in a niche field, attophysics, where they can get a pulse in the low hundred attosecond range, 10 ^ -16 or so.

the fastest time-resolution that is generated is in a niche field, attophysics, where they can get a pulse in the low hundred attosecond range, 10 ^ -16 or so. the signal is extremely weak, the conventional 'shortest-pulse' is around 5 femtoseconds.
