Enhancing multi-gas detectability using photoacoustic spectroscopy capable of simultaneous detection, highly selectivity and less cross-interference is essential for dissolved gas sensing application. A T-type cell was designed verified to be an appropriate sensor, due the resonant frequencies which are determined jointly by absorption cylinders. The three designated resonance modes were investigated from both simulation experiments present comparable amplitude responses introducing...
A sulfur dioxide (SO2) gas sensor based on the photoacoustic spectroscopy technology in a hexafluoride (SF6) matrix was demonstrated for SF6 decomposition components monitoring power system. passive Q-switching laser diode (LD) pumped all-solid-state 266 nm deep-ultraviolet exploited as excitation source. The signal amplitude is linear related to incident optical power, whereas, random jitter inevitable since immature manufacturing UV spectral region. compact stabilization system developed...
Comprehensive sevoflurane monitoring (CSM, concentrations from parts per billion to percent) is essential for the therapeutic diagnosis of anesthetized patients and occupational exposure monitoring. Photoacoustic spectroscopy, with its advantages high sensitivity, wide dynamic range, miniaturization, real-time, holds unique potential CSM. A highly sensitive resonator a small volume an optimal choice regarding limited exhaled gas amount. Wavelength modulation not suitable detecting trace...
The cavity form of complex microcavity lasers predominantly relies on disordered structures, whether found in nature or artificially prepared. These characterized by disorder, facilitate random lasing through the feedback effect boundary and internal scattering medium via various mechanisms. In this paper, we report a fiber laser employing cladding affixed to inner hollow-core fiber. flowing liquid gain establishes stable liquid-core waveguide environment, enabling long-term directional...
