Abstract

We give an overview of near IR laser diode based methods for gas sensing discussing both the devices enabling this technology and the techniques utilised. Of particular importance for this technology is development of single frequency laser diodes for laser based gas sensing. We will discuss and present results on laser diode based gas sensing using sources such as distributed feedback laser diodes, vertical cavity laser diodes and other novel single frequency devices. Detection limits for particular gases of interest, e.g. methane, oxygen and hydrogen sulphide will be discussed.
