We report the compression of intense, carrier-envelope phase stable mid-IR pulses down to few-cycle duration using an optical filament. A filament in xenon gas is formed by using self-phase stabilized pulses at produced via difference-frequency generation in a Ti:sapphire-pumped optical parametric amplifier. The ultrabroadband carrier-wavelength output is self-compressed below 3 optical cycles and has a pulse energy. The self-locked phase offset of the difference-frequency field is preserved after filamentation. This is to our knowledge the first experimental realization of pulse compression in optical filaments at mid-IR wavelengths .
