We present an ultra-broadband optical parametric chirped-pulse amplification (OPCPA) system operating at 3.4 mu m center wavelength with a peak power of 75 MW. The OPCPA system is split into a pre- and a power-amplifier stage. Both stages are based on apodized aperiodically poled MgO:LiNbO3 (APPLN). The collinear mixing configuration allows us to manipulate the spectral phase of the output mid-infrared pulses by sending the near-infrared seed pulses through a pulse shaper. The system delivers clean 75-fs pulses with record-high 700 mW average power, corresponding to 7 mu J of pulse energy at a repetition rate of 100 kHz. (C)2012 Optical Society of America
