“…While the applicability of the Innoslab concept for the amplification of picosecond pulses has been demonstrated 10 years ago on the basis of neodymium doped laser crystals [1] significant progress has been achieved with ytterbium as laser active ion. Sub-picosecond pulsed radiation with more than 600W from a single amplification stage and more than 1.1kW average power from two coupled amplifier stages has been demonstrated at a fixed repetition rate [2].…”

A flexible ultrafast laser amplifier system based on Ytterbium Innoslab technology with an average power exceeding 200W is presented. The pulse duration of the system can be continuously tuned between 500fs and 6ps, limited only by the amplification bandwidth of Yb:YAG and the stretcher of the seed source. The repetition rate can be varied from 26.6MHz down to 1MHz. For the ps-regime more than 200J and for the fs-regime more than 50J are demonstrated without the need of temporal compression of the high power beam after the amplifier. Spectral bandwidth is close to the transform limit of the shortest measured pulses. Beam quality is measured to be near the diffraction limit (M2<1.3)

The InnoSlab concept was developed at Fraunhofer ILT more than 15 years ago using Nd‐based laser crystals. InnoSlab is a highly efficient amplification setup that allows for an extremely broad range of laser parameters due to its inherently simple setup. Today InnoSlab using Yb‐based laser crystals is the leading amplifier technology for achieving highest output power in the ultrashort pulse regime.
