We demonstrate that full temporal characterisation of few-cycleelectromagnetic pulses, including retrieval of the carrier envelope phase(CEP), can be directly obtained from Frequency Resolved Optical Gating (FROG)techniques in which the interference between non-linear frequency mixingprocesses is resolved. We derive a framework for this scheme, defined RealDomain-FROG (ReD-FROG), as applied to the cases of interference between sum anddifference frequency components and between fundamental and sum/differencefrequency components. A successful numerical demonstration of ReD-FROG asapplied to the case of a self-referenced measurement is provided. Aproof-of-principle experiment is performed in which the CEP of a single-cycleTHz pulse is accurately obtained and demonstrates the possibility for THzdetection beyond the bandwidth limitations of electro-optic sampling.
