The simplest and most common method for the characterization of the duration of an ultrashort pulse laser is to measure an autocorrelation function. However, especially with modern high‐power fiber lasers, there are cases where the sensitivity and dynamic range of standard autocorrelators is not sufficient and require more sophisticated measurement methods. With type II autocorrelators, a cost‐efficient high‐contrast technique is available that can provide more detailed insights into a pulse topography that are not visible with normal autocorrelators.
