The black soldier fly (BSF) is recognised as a valuable insect for mitigating feed and organic
waste management challenges. Thus, concerted efforts are being directed toward the …

Optical spectroscopy in the gas phase is a key tool for elucidating the structure of atoms and
molecules and their interaction with external fields. The line resolution is usually limited by a …

In this contribution we review selected point-of-care applications of infrared spectroscopy
and the technological innovations they are based on. After a short introduction summarizing …

Optical feedback exists in most laser configurations and strongly affects laser performances
depending on the feedback strength, length, and phase. In this paper, we investigate the …

A narrow-line-width quantum cascade laser (QCL) is highly demanded for high-resolution
spectroscopy of narrow molecule absorption lines. This work shows a low-noise QCL …

We present the characterization of a novel balanced homodyne detector operating in the
mid-infrared. The challenging task of revealing non-classicality in mid-infrared light, eg in …

A novel study on harmonic frequency combs emitted by quantum cascade lasers (QCLs) is
presented here, demonstrating the presence of intensity correlations between twin modes …

In quantum cascade laser frequency combs, the intensity distribution of the optical spectrum
can be split into two well-separated lobes of longitudinal modes that, even when far apart …

Quantum cascade laser frequency combs are nowadays well-appreciated sources for
infrared spectroscopy. Here their applicability for free-space optical communication is …

Mid-infrared frequency combs are nowadays well-appreciated sources for spectroscopy and
frequency metrology. Here, a comprehensive approach for characterizing a difference …
