The development of mid-infrared, high-energy pulses of extremely short pulse duration is of great importance to the strong field physics community as it enables the extension of the high-harmonic cutoff towards the keV range of photon energies. Here we demonstrate a Cr:ZnSe laser amplifier delivering 7 mJ, 100 fs pulses at 1 kHz repetition rate and 2.4 μm central wavelength with excellent energy stability and beam quality. These pulses are post-compressed to 39 fs, 6.2 mJ and 115 GW peak power in a novel nonlinear compression scheme. The laser system was used to generate coherent soft x-ray radiation up to 0.6 keV covering the entire water window, which is of high importance for bio-relevant applications. The obtained results open a wide range of applications in nonlinear optics, attosecond and strong-field physics, and remote sensing.
