Infrared laser-absorption sensing for combustion gases

TL;DR: SpectraPlot as discussed by the authors is a web-based application for simulating spectra of atomic and molecular gases, including absorption spectra, transition linestrengths, and blackbody emission spectra.

TL;DR: This report reports the first entirely monolithic dysprosium (Dy)-doped fluoride fiber laser operating in the mid-IR region and delivers 10.1 W at 3.24 μm in continuous operation, a record for fiber oscillators in this range of wavelengths.

TL;DR: In this article, a review of the progress in the description of spectral shapes for some practical applications (metrology, probing of gas media, climate predictions) is presented, and the theoretical approaches, results and data proposed (mostly) in the last decade on the topics of isolated line shapes, line-broadening and shifting, linemixing, the far wings and associated continua, and collisioninduced absorption.

TL;DR: The first experimental observation of the dynamic cross-sectional behavior of the swirling flame, enabled by the high spatial and temporal resolutions provided by the TDLAS tomographic imaging system is reported.

TL;DR: Properties of Computerized Tomographic Imaging provides a tutorial overview of topics in tomographic imaging covering mathematical principles and theory and how to apply the theory to problems in medical imaging and other fields.

TL;DR: In this paper, the authors proposed a quantum cascade laser consisting of a gain region (14) consisting of several layers (20) each including: alternating strata of a first type (28) defining each AllnAs quantum barrier and strata with injection barriers interposed between two of the layers.

TL;DR: In this article, the authors present a survey of regularization tools for rank-deficient problems and problems with ill-conditioned and inverse problems, as well as a comparison of the methods in action.

TL;DR: The method works for totally asymmetric objects, and requires little computer time or storage, and is also applicable to X-ray photography, and may greatly reduce the exposure compared to current methods of body-section radiography.
