Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic
spectrum that extends from microwaves to the far infrared (100 GHz–∼ 30 THz). Within its …

Tailoring the electric-field waveform of ultrashort light pulses forms the basis for controlling
nonlinear optical phenomena on their genuine, attosecond timescale. Here we extend …

Measuring transient optical fields is pivotal not only for understanding ultrafast phenomena
but also for the quantitative detection of various molecular species in a sample. Here we …

Optical-field sampling techniques provide direct access to the electric field of visible and
near-infrared light. The existing methods achieve the necessary bandwidth using highly …

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 …

Electrochemical impedance spectroscopy (EIS) is one of the most widely used experimental
tools in electrochemistry and has applications ranging from energy storage and power …

Electro-optic quantum coherent interfaces map the amplitude and phase of a quantum
signal directly to the phase or intensity of a probe beam. At terahertz frequencies, a …

In many states of the quantum electromagnetic field, including the vacuum state,
entanglement exists between different space-time regions—even spacelike separated ones …

The measurement of microwave electric-field (E-field) exposure is an ever-evolving subject
that has recently led the International Commission on Non-Ionizing Radiation Protection to …

Employing electro-optic sampling (EOS) with ultrashort probe pulses, recent experiments
showed direct measurements of quantum vacuum fields and their correlations on subcycle …
