Abstract

In the past years, novel approaches including chirped pulse amplification (CPA) [1] and advanced amplifier architectures such as large pitch fibers [2] have enabled a tremendous increase of the output performance of ultrafast lasers. Today, the potential of these techniques is well exploited. Thus, new technologies are developed, as, for instance, spatio-temporal coherent pulse combination [3], which is a promising and powerful tool, not least because of its scalability. Regarding temporal multiplexing, many different approaches exist [4, 5]. Rectently, a technique named electro-optically controlled divided-pulse amplification (EDPA) [6] has shown promising properties in initial proof-of-principle experiments.
