We have developed several narrow linewidth light sources for gas detection, most lately for atmospheric carbon dioxide detection. An unusual one was based on a diode laser and a tunable grating in silicone elastomer, which was used to measure oxygen in air. In an international project we are developing a UV laser for detection of biological warfare agents.
SFG of green and red to generate UV, visible by the induced blue fluorescence.
