Samples from Australian coal seams were examined by laser-induced fluorescence. Large areas (12.5 mm') of the samples were illuminated with 325, 442, 488 and 514 nm laser beams. The 325 nm laser was more efficient in exciting fluorescence than the longer wavelength lasers. Spectral shifts in the flu
