An optical delay line is the common choice for all applications where the delay in the time domain between 2 or more light-pulses needs to be varied by increments in the femtosecond to nanosecond regime. The difference in path length between 2 beams divided by the speed of light gives the actual time delay. E.g. a difference in path length of 1um equals a time delay of 3.3 fs. (1 um) / (3x10^8 m/s). Note that a movement of the delay stage results in twice the total path length, e.g. 1µm movement of the stage corresponds to 6.6 fs.
