Abstract
We present an ultrafast high-power coherently combined thulium-based fiber-CPA. The laser system aims to deliver 400 µJ pulse energy at a pulse repetition frequency of 500 kHz. The simultaneous availability of 200 W-class average power and 1 GW-class peak power in the 2 µm wavelength regime will not only be unique in the world of science but also will pave the way to more compact, cost-effective lasers which are ideally suited for high-harmonic generation into the water-window and nonlinear-frequency conversion to the mid-IR and THz spectral range.
