This paper describes the first use of novel blue diode lasers to make temperature measurements based on fluorescence. As a demonstration of this principle, indium atoms were seeded as a probe species into flames and the resulting diode laser induced fluorescence allowed an accurate determination of the temperature at a point. This permits spatially resolved measurements to be made, which are impossible to achieve using the established absorption based sensors. The technique opens up a range of application possibilities in dynamic and inhomogeneous reacting flows.
