SYSTEM AND METHOD FOR ISOTOPIC ANALYSIS OF CALCIUM USING LASER INDUCED FLUORESCENCE

摘要

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.

主权项

1. A system configured to detect the relative abundance of isotopes in a sample, each isotope having a characteristic fluorescence wavelength, the system comprising:
a first electro-optical modulator (EOM) of said system configured to receive a first input beam of light and produce therefrom a first frequency-shifted probe beam of light having a first wavelength; a second EOM of said system configured to receive a second input beam of light and produce therefrom a second frequency-shifted probe beam of light having a second wavelength; a first detector positioned in optical communication with the first EOM to acquire first fluorescence induced in a first isotope of the sample when said sample is illuminated with the first probe beam, and a second detector positioned in optical communication with the second EOM to acquire second fluorescence induced in a second isotope of the sample column when said column is illuminated with the second probe beam.
