Continuous development of new coherent light sources operating especially in the Mid-IR spectral band (QCL—Quantum Cascade Lasers, ICL—Interband Cascade Lasers, OPO—Optical Parametric Oscillator, DFG—Difference Frequency Generation, optical frequency combs, etc.) stimulates new, sophisticated methods and technological solutions in this area. The development of clever techniques in gas detection based on new mechanisms of sensing (photoacoustic, photothermal, dispersion, etc.) supported by advanced applied electronics and huge progress in signal processing allows us to introduce more sensitive, broader-band and miniaturized optical sensors. Additionally, the substantial development of fast and sensitive photodetectors in MIR and FIR is of great support to progress in gas sensing. Recent material and technological progress in the development of hollow-core optical fibers allowing low-loss transmission of light in both Near- and Mid-IR has opened a new route for obtaining the low-volume, long optical paths that are so strongly required in laser-based gas sensors, leading to the development of a novel branch of laser-based gas detectors. This Special Issue summarizes the most recent progress in the development of optical sensors utilizing novel materials and laser-based gas sensing techniques.Optical Gas SensingTechnology: general issuesbicsscHistory of engineering & technologybicssclaser flow meterPitot tubeflow speedtime of flightdilution methodflow simulationflow turbulencegas sensing applicationsMEMSgas sensorphotoacousticscantilevercapacitive detectionanalytic modelinfrared imagingmultispectral and hyperspectral imagingair pollution monitoringremote sensing and sensorsspectroscopyfourier transformimage processinglaser gas analyzerflux measurementeddy covariance methodderivative absorption spectroscopygas sensorsantiresonant hollow core fiberslaser spectroscopywavelength modulation spectroscopytunable diode laser absorption spectroscopyphotothermal spectroscopyphotoacoustic spectroscopyfiber gas sensorsmid-infraredquantum cascade detectorhigh-speed operationheterodyne detectionhigh-resolution spectroscopyisotopic ratiofrequency combVernier spectroscopyrefractometrypressureshort-term performanceFabry–Perot cavitygas modulationmodulation techniquesmetrologyintegrated sensorswaveguidesabsorption spectroscopyRaman spectroscopygas sensingfemtosecond laser micromachiningmicrochannel fabricationmicrostructured fibersphotoacousticpressure transducerwafer-levelCO2combined NIR/MIR laser absorptionlaser multiplexing in a mid-IR single-mode fibersimultaneous multispecies (CO, CO2, H2O) in situ measurementsTechnology: general issuesHistory of engineering & technologyAbramski Krzysztof Medt1319553Jaworski PiotredtAbramski Krzysztof MothJaworski PiotrothBOOK9910566467103321Optical Gas Sensing: Media, Mechanisms and Applications3033958UNINA
