ABSTRACT:
In a laser-operated detecting device, the light source of a laser beam applied to a specimen under test is a tunable laser whose wavelength can be continuously tuned in a certain range. The detecting device is realized as a high speed liquid chromatography fluorescence detector, a high speed liquid chromatography Raman detector, a laser Raman spectroscopic measuring device, a coherent anti-Stokes Raman measuring device, or a microscopic Raman measuring device.
