The chirped mirror compressor was set-up such that shortest pulses could be achieved. A GDD of −1700 fs was predicted and realized by 4 bounces off mirrors with −400 fs GDD and no higher order terms. A pulse duration of 43 fs was measured. It is in good agreement with the predicted pulse duration of 46 fs for a slightly more negative GDD. The pulse in Fig. 3.21b shows a significant pedestal structure carrying about 35% total energy which agrees with the prediction in Fig. 3.21a. Larger broadening factors come also with an increase of spatial losses due to the coupling of self-focusing and SPM. This has not been considered in this section but will be addressed in detail in the simulation part of this work.
