Field detection of CO and CH4 by NIR 2f modulation laser spectroscopy
A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...
متن کاملProposal Daniel J . Evans Build - Up Cavity Coupled to a Laser Diode Center of Excellence for Raman Technology
The proposed thesis is to build a power build-up cavity pumped by a laser diode. In Raman spectroscopy there is a need for high power laser diode sources to be used in Raman gas monitoring applications. A high power laser source will allow the development of compact and low cost systems for use in any gas monitoring application where detection into the ppb is necessary. Gas detection can be acc...
متن کاملA review of recent advances in semiconductor laser based gas monitors
When first tunable diode lasers were developed in the mid-1960s they found immediate application as much needed tunable sources for high-resolution laser absorption spectroscopy commonly referred to as TDLAS (tunable diode laser absorption spectroscopy). Substantial improvements in sensitivity and detection speed have been achieved since then and an increasing number of laser based gas monitori...
متن کاملSEMICONDUCTOR LASER BASED TRACE GAS SENSOR TECHNOLOGY: RECENT ADVANCES AND APPLICATIONS Laser Based Trace Gas Sensor Technology
Recent advances in the development of sensors based on infrared diode and quantum cascade lasers for the detection of trace gas species is reported. Several examples of applications in environmental and industrial process monitoring as well as in medical diagnostics using quartz enhanced photoacoustic spectroscopy and laser absorption spectroscopy will be described.
