Did you know? Deeper Insight in Autocorrelation Measurements …
November 5th, 2024In their latest research, Torben Fiehler, Clara Saraceno, Günter Steinmeyer, and Ulrich Wittrock show in detail how you can prevent misinterpretations of autocorrelation measurements.
Spectrally broad laser radiation from continuous wave (cw) lasers can produce second-order autocorrelation traces that closely resemble those of mode-locked lasers.
By using the APE pulseCheck autocorrelator, the authors compared measured autocorrelations and calculations of a mode-locked Ti:Sa laser with a spectrally broad, monolithic cw Ti:Sa laser, devising a new method to safeguard against autocorrelation misinterpretations.
Many thanks to the authors for their important findings!
