Abstract

The invention relates to a method for determining the relative temporal position of electromagnetic pulses. Said method having the steps generating a sequence of first electromagnetic pulses, generating a sequence of second electromagnetic pulses, overlaying at least a part of the first and the second pulses in a saturable absorber, detecting the second pulses that have passed through the saturable absorber by means of a detector in such a manner that the second pulses, but not the first pulses that have passed through the saturable absorber, are detected, and determining the temporal position of the first pulses relative to the temporal position of the second pulses with the aid of a signal from the detector which is generated when the second pulses that have passed through the saturable absorber are received.
