We demonstrate experimentally for the first time a ~40-µJ two-octave-wide passively carrier-envelope phase (CEP)-stable parametric front-end seeding an ytterbium (Yb)-pump-based, few-optical-cycle, high-energy optical waveform synthesizer. The system includes CEP-stable white-light continuum and two-channel chirped pulse amplifiers (OPCPAs) in near- mid-infrared spectral regions spanning altogether spectrum driven by regenerative amplifier. output pulses are compressed fully characterized to well-behaved of this seed source.
