Intense Terahertz Excitation of Semiconductors presents the first comprehensive treatment
of high-power terahertz applications to semiconductors and low-dimensional semiconductor …

We will ask and partly answer a few questions. What is the difference between a laser and a
light bulb? In which frequency ranges are lasers available? Which are the sizes and the …

ABSTRACT Free‐Electron Lasers (FELs) collectively operate from the terahertz through the
ultraviolet range and via intracavity Compton backscattering into the X‐ray and gamma‐ray …

We have directly determined the spectral shape of the complex conductivities of Bloch
oscillating electrons by using the time-domain terahertz (THz) electro-optic sampling …

We show that a tilted magnetic field transforms the structure and THz dynamics of charge
domains in a biased semiconductor superlattice. At critical field values, strong coupling …

Esaki and Tsu's superlattice, made by alternating two different semiconductor materials, was
the first one-dimensional artificial crystal that demonstrated the ability to tailor semiconductor …

Electrons performing Bloch oscillations in an energy band of a dc-biased superlattice in the
presence of weak dissipation can potentially generate THz fields at room temperature. The …

The detailed theoretical study of high-frequency signal gain, when a probe microwave signal
is comparable to the AC pump electric field in a semiconductor superlattice, is presented …

Parametric generation of oscillations and waves is a paradigm, which is known to be
realized in various physical systems. Unique properties of quantum semiconductor …

We theoretically analyze the influence of magnetic field on small-signal absorption and gain
in a superlattice. We predict a very large and tunable THz gain due to nonlinear cyclotron …
