Open the CIPO recordAbstract From the Canadian patent
Gases in the atmosphere are detected remotely using a Raman-shifted excimer/dye laser beam formed by passing an excimer/dye laser beam through a circulating-medium Raman-shifting cell which significantly increases the measurement repetition rate and allows for the production of an infinite number of different wavelengths for measurement. The Raman-active medium is continously circulated so that the inputted laser beam passes through the Raman-active medium when the molecules of the medium in the optical path are at their ground energy level state. The Raman cell is then tuned to provide a first wavelength, preselected for nonabsorption by the gases to be detected which is, transmitted …
