  • Method and apparatus for evaluating the quality of an optical crystal
    Patent number: 6486949
    Abstract: A method for evaluating the quality of an optical material includes obtaining a fluorescence spectrum of the optical material, obtaining a fluorescence spectrum of a reference material having desired performance in a target application, and determining whether a shape of the spectrum of the optical material is similar to a shape of the spectrum of the reference material. If the shape of the spectrum of the optical material is similar to the shape of the spectrum of the reference material, the method includes indicating that the optical material is suitable for the target application; otherwise, the method includes indicating that the optical material is unsuitable for the target application.
    Type: Grant
