“…Short optical probe pulses have been used to sample the electric field of waveforms from THz to MIR and recently to visible spectral range by EOS [24,59,73,[112][113][114][115][116][117][118][119]. In EOS, gate pulses and sample pulses propagate collinearly in a nonlinear crystal.…”

“…As a result, two waves are generated: a local oscillator (LO) resulting from nonlinear propagation of the gate pulse in the crystal, and a signal, which is the result of nonlinear mixing of both input pulses. These waves pass through a polarizer and a spectral filter and are detected using a photo diode [59].…”

The ability to resolve the complete electric field of laser pulses from terahertz to mid-infrared spectral ranges has enriched time-domain spectroscopy for decades. Field-resolved measurements in this range have been performed routinely in ambient air by various techniques like electro-optic sampling, photoconductive switching, field-induced second harmonic generation, and time stretch photonics. On the contrary, resolving the electric field of light at the near-infrared spectral range has been limited to attosecond streaking and other techniques that require operation in vacuum. Recent advances are circumventing these shortcomings and extending the direct, ambient air field detection of light to petahertz frequencies. In the first part of this letter, recent field-resolved techniques are reviewed. In the second part, different approaches for temporal scanning are discussed, as the temporal resolution of the time-domain methods is prone to temporal jitter. The review concludes by discussing technological obstacles and emerging applications of such advancements.
