For emerging real world applications the availability of high repetition rate and high energy ultrashort pulse laser systems is of significant importance. Ytterbium-doped fiber laser systems have established themselves as a very attractive gain medium for pulsed amplification. We discuss the feasibility of high average power (>100 W) and high energy (~100 μJ) femtosecond fiber CPA systems. Novel fiber geometries based on microstructured large-core air-clad fibers are introduced, which allow for a significant performance scaling. Furthermore, an all- fiber CPA system including an air-core photonic band-gap fiber compressor is presented. This approach opens the avenue to a completely fiber integrated high performance short pulse laser system.
