X.2015-07-282015-07-2820090146-9592http://hdl.handle.net/11693/11837We present a 9 GW peak power, three-cycle, 2.2 mu m optical parametric chirped-pulse amplification source with 1.5% rms energy and 150 mrad carrier envelope phase fluctuations. These characteristics, in addition to excellent beam, wavefront, and pulse quality, make the source suitable for long-wavelength-driven high-harmonic generation. High stability is achieved by careful optimization of superfluorescence suppression, enabling energy scaling. (C) 2009 Optical Society of AmericaEnglishArticle10.1364/OL.34.0016391539-4794
