Abstract

The disclosure relates to the measurement of temporal characteristics of optical pulses. Embodiments may be used for single-shot characterization of picosecond optical pulses. The optical pulse may be split into a plurality of ancillary pulses. Amounts of distortion may be added to the plurality of ancillary pulses. An instantaneous power of the plurality of ancillary pulses may be measured. Thereafter, an experimental trace with the measured instantaneous powers may be constructed and the experimental trace may be outputted. The experimental trace may be processed to calculate temporal characteristics of the input optical pulse. A fiber assembly may be used to split the pulse into the plurality of ancillary pulses. The fiber assembly may include one or more splitters. The one or more splitters may direct the ancillary pulses along different optical paths having different lengths to temporally separate the ancillary pulses and to add amounts of distortion.
