We realize a multicolor, multi-cycle combination of commonly CEP-locked three waves from a single femtosecond OPA and report HHG driving with individual and combined colors. Employing a novel multicolor multi-cycle incommensurate-frequency waveform synthesizer we demonstrate a previously theoretically predicted capability to enhance the cut-off position of the HHG spectrum and upscale the XUV flux as compared to single-color driving.
