Continuous wave generation of coherent vibrational anti-stokes spectra |
摘要 |
A method and apparatus for spectroscopic material analysis are provided. Two coherent, continuous beams of monochromatic radiation are directed through a sample of material. A tuning mechanism adjusts the frequency difference between the radiation beams to equal substantially the vibrational frequency of a preselected constituent of the material. Radiation scattered by the material is received by a filtering mechanism adapted to transmit selectively an anti-Stokes signal generated coherently during scattering. The signal is received by a detecting mechanism which indicates the intensity thereof.
