Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

Strong optical pulses at mid-infrared and terahertz frequencies have recently emerged as
powerful tools to manipulate and control the solid state and especially complex condensed …

Extreme nonlinear interactions of THz electromagnetic fields with matter are the next frontier
in nonlinear optics. However, reaching this frontier in free space is limited by the existing …

Terahertz electromagnetic radiation is extremely useful for numerous applications, including
imaging and spectroscopy. It is thus highly desirable to have an efficient table-top emitter …

This year the discovery of femtosecond demagnetization by laser pulses is 20 years old. For
the first time, this milestone work by Bigot and coworkers gave insight directly into the time …

In this paper, we will review both past and recent progresses in the generation, detection
and application of intense terahertz (THz) radiation. We will restrict the review to laser based …

The understanding of how spins move and can be manipulated at pico-and femtosecond
timescales has implications for ultrafast and energy-efficient data-processing and storage …

Spin-based technologies can operate at terahertz frequencies but require manipulation
techniques that work at ultrafast timescales to become practical. For instance, devices based …
