Paper Abstract

We report the in situ characterization of a semiconductor saturable absorber mirror (SESAM) in an operating Yb:KGW mode-locked laser. The technique may be described as a pump-probe experiment in which the intracavity beam acts as a pump beam, while the output of the same laser is used as a test beam for the SESAM reflectivity. At zero delay, the probe pulse overlaps in time with the subsequent intracavity pulse. The method is an alternative to standard pump-probe measurements, in situations where the intracavity parameters such as energy fluence onto the SESAM, pulse length and center wavelength can not be simultaneously achieved with available lasers.
