SPECTROSCOPIC APPARATUS USING SPECTRUM NARROWED AND STABILIZED LASER WITH BRAGG GRATING |
摘要 |
An apparatus for measuring properties of physical matters by means of Raman spectroscopy including a laser element (1), a wavelength dispersion element (4), an array or single element detector (5), and a control and data processing unit (6). The laser element (I)1 which is used to excite Raman scattering, is spectrum narrowed and stabilized by attachment of a Bragg grating device. The grating can be either a volume Bragg grating (VBG) written inside a glass substrate or a fiber Bragg grating (FBG) written inside an optical fiber. A laser element can be provided with a wavelength modulation capability for fluorescence background suppression. |
