Keywords:pulse compression, mid-infrared pulse, optical parametric amplifier

We demonstrate multiple-plate compression of mid-infrared multi-cycle pulses (3.5 μm, 120 μJ, 120 fs) generated from an optical parametric amplifier. We found empirically that a combination of 2 mm AR-coated Si, 2 mm YAG and 1 mm AR-coated Si plates efficiently broadens the spectrum of the femtosecond MIR pulses. 21 fs pulse duration (1.8-optical-cycle) is achieved by subsequent chirp-compensation by a pair of CaF2 wedges.
