THZ PUMP-PROBE SPECTROSCOPY WITH A DELAY WHICH CAN BE SET BY THE REPETITION RATE

摘要

The invention relates to a method for generating two delayed pulses, in particular in terahertz spectroscopy and/or in pump-probe experiments, with the following method steps: - generating a pulsed beam using a beam source (1), in particular a pulsed laser; - dividing the pulsed beam (2), wherein the first partial beam (4) comprises a first pulse and the second partial beam (5) comprises a second pulse; - directing the two pulses onto a respective target area (9, 10), wherein the first pulse directly reaches a first target area (9) and the second pulse reaches a second target area (10) after passing through a delay path, and wherein the two target areas can be coincident; - using the two pulses, particularly for a measurement method; wherein the time delay of the two pulses in the respective target area can be set by the pulse repetition rate of the pulsed beam (2).
