Investigation of Laser-Induced Fluorescence in Commercial Glass Samples
EMSL Project ID
2024
Abstract
Glass containing iron ions fluorescences when irradiated with light at 380 nm. The fluorescence lifetime is temperature dependent and either lifetime measurements or total fluorescence signal measurements can be correlated to glass temperature. We intend to demonstrate a temperature diagnostic that can measure glass temperature up to 600 C with an accuracy of about 5 C. The concept has been demonstrated with low power laser systems but with insufficient dynamic range and accuracy. We would like to repeat the experiments using the frequency-doubled Alexandrite laser available at EMSL. We now have glass samples from the auto industry and the TV glass industry ready for testing and have improved the glass heating hardware and are very nearly ready to go.
