Hereby, more and more studies focus on the influence of the pulse duration and pulse shape on the material processing mechanisms. Commonly the behaviour of the pulse is defined by the temporal width. Considering a Sech2 or Gaussian-like pulse shape, the peak power and peak intensity of the laser pulse can be calculated. Nevertheless, this assumption ignores the fact that real laser pulses can feature long picosecond pulse trails below the main femtosecond peak, which are typically hard to measure with standard, commercially available devices like collinear SHG-autocorrelators. Here we present various pulse measurements with the novel high-contrast autocorrelator from APE GmbH, demonstrating its capabilities and advantages in identifying the real pulse energy which is contained in the femtosecond main peak.}, subject = {Autokorrelation}, language = {de} }
