Zusammenfassung:A compact Raman probe integrated with a wavelength-stabilized laser source is disclosed. The output beam of the laser source has an elongated cross-section that is focused onto a target of interest. Raman and Rayleigh scattered light is collected, collimated, and filtered by free-space optics to form a beam that is coupled to the input of a multimode optical fiber having an elongated core that is aligned to edge slits of an optical spectrometer.
