"Splet12. apr. 2024 · Consequently, the signal is generated only during a brief window of time, comparable to the length of the laser pulses. At such short time delays, pulses overlap, and light–matter interactions do not need to follow the time-ordering of the pulses. These out-of-sequence interactions can then lead to false signals. 35 35. D. " - Short optical pulses
