In this work, we fill the existing gap in subcycle lightwave electronics by demonstrating a robust, all-solid-state approach for the generation of microjoule subcycle pulses in the mid-infrared. We have demonstrated an approach for the generation of 20-fs-pulses at 6.8 mkm. Subcycle pulse widths have been achieved due to self-compression dynamics and ultrabroadband phase matching for four waves mixing near the zero-GVD wavelength of GaAs
