Multiplex coherent raman spectroscopy detector and method |
| abstract |
A multiplex coherent Raman spectrometer ( 10 ) and spectroscopy method rapidly detects and identifies individual components of a chemical mixture separated by a separation technique, such as gas chromatography. The spectrometer ( 10 ) and method accurately identify a variety of compounds because they produce the entire gas phase vibrational Raman spectrum of the unknown gas. This is accomplished by tilting a Raman cell ( 20 ) to produce a high-intensity, backward-stimulated, coherent Raman beam of 683 nm, which drives a degenerate optical parametric oscillator ( 28 ) to produce a broadband beam of 1100-1700 nm covering a range of more than 3000 wavenumber. This broadband beam is combined with a narrowband beam of 532 nm having a bandwidth of 0.003 wavenumbers and focused into a heated windowless cell ( 38 ) that receives gases separated by a gas chromatograph ( 40 ). The Raman radiation scattered from these gases is filtered and sent to a monochromator ( 50 ) with multichannel detection. |
