  • System and method for isotopic analysis of calcium using laser induced fluorescence
    Patent number: 10302565
    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.
    Type: Grant
    Filed: February 18, 2015
    Date of Patent: May 28, 2019
    Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY

  • Sub-doppler intermodulated laser-induced-fluorescence spectrometer
    Patent number: 9976955
    Abstract: Optical spectroscopy system and method possessing spectral selectivity sufficient to distinguish isotopic line of the metal of interest. Each of the light beams, counter-propagating through vial with vapor of the sample, has been originated from the same light output of the laser source and modulated at a corresponding judiciously-determined frequency. The light-output, in turn, possesses a carrier frequency and two side-band frequencies defined with respect to a mean value of excitation frequencies of isotopes in the vapor.
