We propose a new method to generate the carrier-envelope phase stable, > 200 µJ, ~ 1.1-cycle laser pulses at 2 µm wavelength, based on an optical parametric amplifier with the optimized angular dispersion. The angularly dispersed non-collinear angle is optimized over the entire bandwidth from 1.3...
