The Innoslab Laser Platform - ns to fs pulse duration at kW class output power — •Dieter Hoffmann, Peter Rußbüldt, Marco Höfer, Peter Loosen, and Reinhart Poprawe — Fraunhofer Institut für Lasertechnik, Aachen, Steinbachstraße 15

With the Innoslab concept a new fundamental platform for highly efficient and compact laser oscillators and amplifiers has been developed and continuously improved in the past 15 years. Starting with partially end-pumped lasers with a line-shaped pump cross section in 1996, the continuous performance improvement led to of a series of output power records for short and ultrashort pulsed lasers. For example 120 mJ pulse energy at sub ns pulse duration and 1.3 kHz prf has been demonstrated based on a Nd:YAG MOPA. With a Yb:YAG MOPA more than 1 kW output power at 600 fs pulse duration has been demonstrated. Further power scaling to multi kW level, generation of sub 400 fs pulses and a new Innoslab design of an extremely compact planar geometry are currently in progress. The presentation provides an overview over the most important Innoslab results and gives an outlook on promising next development steps.
