Abstract
The commercial availability of laser diodes emitting in the blue spectral region offer excellent opportunity for using them in the detection of nitrogen dioxide (NO2) gas. Nitrogen dioxide, which is one of the main air pollutants, has strong light absorption cross-section in the blue spectral region. In this paper, a tunable blue diode laser in Littrow external-cavity configuration is investigated. The output power, spectral line-width and tunable range are measured. The results will be used to select a suitable external cavity diode laser (ECDL) system based on a multimode blue laser diode to be employed for the detection of NO2 gas.
