Abstract
Official abstract text for this publication.
The invention relates to a crystal fiber, a Raman spectrometer using the same and a inspection method thereof. The crystal fiber comprises a sapphire crystal is doped with two transition metals having different concentrations. An excitation light beam at a specific wavelength can propagate along the crystal fiber to generate a narrow-band light beam and a wide-band light beam to project on a specimen. Raman scattered light is emitted from the specimen. The wavelength of the Raman scattered light falls within the wavelength range of the wide-band light beam so that the wide-band light beam is enhanced at some characteristic wavelengths to facilitate Raman spectroscopy.
First claim
Opening claim text (preview).
What is claimed is: 1. A crystal fiber, comprising: a sapphire crystal having a core, the core comprising a first transition metal and a second transition metal, wherein the concentration of said first transition metal is different from the concentration of said second transition metal, whereby said first and said second transition metals generate a narrow-band light beam and a wide-band light beam simultaneously when an excitation light passes through said crystal fiber.…
