In the last couple of decades, terahertz (THz) technologies, which lie in the frequency gap
between the infrared and microwaves, have been greatly enhanced and investigated due to …

Optical nonlinear conversion processes are ubiquitously applied to scientific as well as
industrial tasks. In particular, nonlinear processes are employed to generate radiation in …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

Tunability has added an important dimension to a variety of laser devices and led to new
systems and applications. From laser spectroscopy to Bose-Einstein condensation, the one …

We present a continuous wave terahertz source based on intracavity difference frequency
generation within a dual color vertical external cavity surface emitting laser. Using a …

Generation of high‐power radiation in terahertz frequency range 0.3–10 THz is a fast
developing research area attracting considerable interest over the past years due to its …

The use of laser pulse sequences to drive the cascaded difference frequency generation of
high energy, high peak-power and multi-cycle terahertz pulses in cryogenically cooled (100 …

We demonstrate experimentally the efficiency of a recently proposed scheme of terahertz
generation based on Cherenkov emission from ultrashort laser pulses in a sandwich …

Optoelectronic techniques for generation and detection of terahertz (THz) signals have been
reviewed. The operation principles of THz photomixer sources and THz parametric sources …

We demonstrate, to the best of our knowledge, a novel generation process of a terahertz
(THz) electromagnetic wave via a noncollinear χ^(2) process in LiNbO_3 with a phase-front …
