We performed femtosecond two-color experiments (four-wave mixing and pump probe) using two independently tunable, partially synchronized femtosecond lasers. Despite the fact that the jitter is of the order of 5–10 ps, the time resolution is limited only by the pulse width when a homemade sample-and-hold switch is used.
