ABSTRACT:
In a pump/probe experiment, information about an event is detected and correlated with an accumulatable quantity representing the elapsed time interval between the arrival of the pump and probe pulses at the experiment. The accumulatable quantity is used to configure the pump and probe sources to eliminate temporal resolution problems caused by pulse timing jitter, the complexity of amplification, continuum generation, and subsequent reamplification, as well as data acquisition rate limitations. Two pulse sources serve as pump and probe pulses respectively. Each pulse is directed at the experiment. A portion of each pump pulse is diverted to a detector before it reaches the experiment, and a portion of each probe pulse is diverted to another detector. The pump and probe pulses are no-coincident in time at the experiment. Quantities related to the time difference and the information imposed on the probe pulse by the experiment are accumulated to obtain data about the temporal evolution of the event.
