Mid-IR spectroscopy with quantum- cascade lasers and difference-frequency based spectrometers The advantages of direct absorption detection can be better exploited when one moves towards longer wavelengths. After the advent of quantum cascade lasers, several QCL-based spectrometers were success- fully used, either in pulsed or continuous mode, for absorption spectroscopy as well as isotopic detection of species whose transitions are not ac- cessible to conventional room-temperature diode lasers (Webster et al., 2001; Kosterev and Tittel, 2002). keywords: absorption; frequency; gas; laser; measurements; natale; quantum; spectrometer cache: annals-3232.pdf plain text: annals-3232.txt item: #130 of 1111 id: annals-3233 author: Barbara title: Vol48/04/2005def date: 2006-02-09 words: 6177 flesch: 60 summary: Increasing the amount of SiF4 in the gas phase in response to 1) a higher fluorine activity in the vapour, or 2) lower gas temperatures would in- crease the amount of SiO2 formed.
