In the field of absorption spectroscopy, the multipass cell (MPC) is one of the key elements. It
has the advantages of simple structure, easy adjustment, and high spectral coverage, which …

In this paper, we report on the performance of quartz tuning fork (QTF) based laser
spectroscopy sensing employing multiple QTFs. To avoid that resonance frequency …

This invited review paper summarizes and discusses developments of QTF based state-of-
the-art quartz-enhanced photoacoustic spectroscopy (QEPAS) and quartz-enhanced …

An H-shaped acoustic micro-resonator (AmR)-based quartz-enhanced photoacoustic
spectroscopy (QEPAS) sensor is demonstrated for the first time. The H-shaped AmR has the …

An acoustic microresonator (AmR) based in-plane quartz-enhanced photoacoustic
spectroscopy (IP-QEPAS) sensor with a line interaction mode is proposed for what is …

A trace gas detection technique of quartz-enhanced photoacoustic-photothermal
spectroscopy (QEPA-PTS) is demonstrated. Different from quartz-enhanced photoacoustic …

A multi-quartz-enhanced photothermal spectroscopy (M-QEPTS) based trace gas detection
method is reported for the first time. Different from traditional QEPTS sensor employing a …

In this paper, a hollow-core anti-resonant fiber (HC-ARF) based light-induced thermoelastic
spectroscopy (LITES) sensor is reported. A custom-made silica-based HC-ARF with length …

An ultra-high sensitive light-induced thermoelastic spectroscopy (LITES) sensor based on a
resonant high Q-factor quartz turning fork (QTF) and a Herriot multipass cell was …

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 …
