“…In recent years the detection of a series of important trace gases has been demonstrated with these devices. (Faist, et al, 1994(Faist, et al, ,1997Beck et al, 2002;Silva et al, 2004;Baptista-Filho et al, 2006;Lima et al, 2006;Grossel et al, 2007;Gmachl et al, 2001;Beyer et al, 2003;Curl et al, 2010;. By way of illustration we report on measurements of sulphur hexafluoride and methane with a homemade Laser Photoacoustic Spectrometer equipped with QC lasers and a Differential Photoacoustic Cell.…”

“…The QCL laser coupled with a photoacoustic detector has been successfully used to measure the concentration of different gases which absorb radiation in the mid-infrared spectral region, such as ozone (Silva et al, 2004), ammonia (Baptista-Filho et al, 2006), and NO 2 and N 2 O gases. (Lima et al, 2006;Grossel et al, 2007) This type of laser is part of the family of semiconductor lasers, with the particularity of using quantum transitions within the same band. A quantum cascade laser comprises a series of alternate thin layers of two different materials.…”

“…Several optical techniques have been developed to detect these hazard gases in the atmosphere [3][4][5][6][7][8][9][10]. Cavity-enhanced spectroscopy (CEAS) or cavity ring-down spectroscopy (CRDS) has been demonstrated to enable measurements of multiple gases with a low detection limit of sub-ppb [4][5][6].…”

Due to the fact of global warming, air quality deterioration and health concern over the past few decades, great demands and tremendous efforts for new technology to detect hazard gases such as CH 4 ,C O 2 , CO, H 2 S, and HONO have been performed. Tunable diode laser absorption spectroscopy (TDLAS) is a kind of technology with advantages of high sensitivity, high selectivity, and fast responsivity. It has been widely used in the applications of greenhouse gas measurements, industrial process control, combustion gas measurements, medicine, and so on. In this chapter, we will briefly summarize the most recent progress on TDLAS technology and present several kinds of gas sensors developed mainly by our group for various field applications. These could expand from energy, environment, and public safety to medical science.

“…Several laser sources, such as lead-salt diode laser, quantum cascade laser [3], colorcenter laser, Raman lasers [4,5] and optical parametric oscillator (OPO) [6,7], can emit CW laser radiations in the mid-infrared region. However, all these sources have their own issues when they are put into practical applications.…”

Abstract:In this paper we report a fiber-type widely tunable CW mid-IR DFG/QPM laser source based on periodically poled MgO-doped LiNbO 3 (PPMgLN), which uses a ytterbium-dope fiber laser (YDFL) as the pump source and a tunable erbium-dope fiber laser (EDFL) cascaded with an erbium-doped fiber amplifier (EDFA) as the signal source. Our experimental results show that, with the PCs to adjust the pump and signal polarization orientations being parallel to the crystal principle optical axis the conversion efficiency may be optimized. The pump and signal beam spots and their longitudinal evolution behaviors determine the RCE and the crystal longitudinal position tolerance, which are measured to be 0.717 (mW) −2 and 44 mm for the mid-IR laser source, respectively. The idler output of the mid-IR DFG/QPM laser source may be continuously tuned from 3.1 to 3.6 μm with almost the same RCE.Idler output
