Abstract: 1,145,506. Laser raman spectroscopy. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. July 22, 1966 [July 27, 1965], No.33142/66. Heading G2J. The inverted Raman spectrum of a substance i.e. the reverse process to the stimulated Raman emission which is observed on absorption and which occurs only when an intense continuous spectrum and a monochromatic line of very high intensity exist simultaneously in the substance is produced by providing a triggered laser 1 whose beam is focused by lens 2 in a tank 3 containing a gas under pressure such as krypton or xenon at a pressure of ten atmospheres, so as to cause emission of an intense continuous spectrum extending from the infrared to the ultraviolet, reducing the energy of the laser beam below but close to, the threshold at which stimulated Raman emission occurs in the substance being investigated, focusing the resulting composite beam by a lens 6 in the substance in a tank 7 so that the output impinges on a diffuser 8 and projecting by lens 9, an image of diffuser 8 on to the inlet slit of a spectrograph 10. The energy of the laser beam may be reduced to the required level by passing through one or more additional tanks 5 containing gas under pressure which are similar to tank 3. The beam may be passed several times through tank 7 so as to be focused at several different points within the tank, Fig. 2 (not shown).
