Abstract: Laser-induced fluorescence based optical system and method configured to precisely quantify the relative abundances of calcium (Ca) isotopes in a sample. Optionally, a diode laser is used as a laser source, with its output frequency shifted by two electro-optical modulators to optically excite fluorescence in the calcium-containing sample. The amounts of fluorescence emitted by the various isotopes are measured and compared.
