This book provides a cutting-edge research overview on the latest developments in the field
of Optics and Photonics. All chapters are authored by the pioneers in their field and will …

Since the demonstration of the first quantum cascade laser (QCL) in 1997, QCLs have
undergone considerable developments in output power, wall plug efficiency (WPE), beam …

We review the recent developments in precision ro-vibrational spectroscopy of buffer-gas-
cooled neutral molecules, obtained using infrared frequency combs either as direct probe …

The demand for tunable terahertz (THz) generating laser sources is significantly growing as
they are used in a wide range of applications including THz imaging, spectroscopy, and …

In this paper, we propose an electrically driven optically excited laser structure for terahertz
(THz) generation in quantum cascade lasers (QCLs) through frequency down-conversion …

Engineering a Terahertz (THz) frequency comb spectroscopy at atomic level advances the
precisely measurement in spectroscopy and sensing. Current progresses on THz frequency …

The interband cascade laser (ICL) is an ideal candidate for low-power mid-infrared
frequency comb spectroscopy. In this work, we demonstrate that its intracavity second-order …

We propose a method to generate stabilized radio-frequency polarization modulation based
on optical frequency combs. Two pulse trains with the same repetition rate and different …

We develop a theoretical model for a tunable coherent terahertz radiation source based on
the long-lived Bose condensate of photons. In the device we propose, the original photon …

Longtime restricted to the field of astronomy, the recent exploitation of electromagnetic
waves at terahertz frequencies (1 THz= 10^ 12 Hz) has highlighted an interest in other areas …
