Rapid detection technology for human and animal diseases is essential in human health
and animal production, most of which are invasive. Accompanying the development of …

Dual-comb spectroscopy (DCS) has revolutionized optical spectroscopy by providing
broadband spectral measurements with unprecedented resolution and fast response …

Antiresonant Hollow-Core Fibers (ARHCFs), thanks to the excellent capability of guiding
light in an air core with low loss over a very broad spectral range, have attracted significant …

We demonstrate a robust and miniaturized fiber Fabry-Perot cavity-based sensor for
photothermal spectroscopic signal retrieval. The proof-of-concept experiment involved the …

Laser-based gas sensors are undergoing constant and rapid development due to their
usability in numerous applications focused on eg monitoring of greenhouse gases …

Photothermal spectroscopy with the optical pump-probe configuration has been used for
sensitive gas detection in hollow-core fibers. In this study, we demonstrate a new method of …

We report a compact mid-infrared (MIR) photothermal spectroscopic ethane (C_2H_6)
sensor with a hollow-core negative-curvature-fiber (HC-NCF) gas cell. The HC-NCF …

We present the first mid-infrared optical frequency comb spectrometer employing an
absorption cell based on self-fabricated, all-silica antiresonant hollow-core fiber (ARHCF) …

Photothermal interferometry (PTI) spectroscopy is a background-free and ultrasensitive gas
or chemical sensing method. To date, most works have focused on applying different …
