Monitoring of gaseous pollutants by tunable diode lasers
This publication is divided into four sections: (i) atmospheric trace gas detection; (ii) diode lasers and their properties, including progress in IV-VI physics and optoelectronic devices; (iii) techniques, systems, components; (iv) special applications. Atmospheric trace gas detection is of central interest, and the impressive capabilities of the diode laser technique are clearly demonstrated. Reports on IV-VI mid-infrared diode lasers stress those properties which are essential for application to ultra-high sensitivity pollution monitoring - radiation noise and emission linewidth. Two reports on III-V systems emitting at wavelengths shorter than 3 microns show that the less severe cooling requirements can lead to more compact equipment which can be used to detect pollutants via overtone absorption bands. The presentations on IV-VI physics and devices stress the physical and technological aspects of mid-infrared diode lasers. Laterally structured diode lasers are discussed in detail. There is also extensive material comparing the traditional AM and more recent FM techniques, while the reports on special applications point to new directions for research.
