    • The invention relates to a method and a device for producing and detecting a Raman spectrum. The problem addressed by the present invention is that of devising a method and a device for producing and detecting a Raman spectrum of a medium under investigation, whereby the Raman spectrum of a medium that is under investigation can be examined with a high degree of sensitivity while requiring relatively little equipment. The method is characterized by the coupling of excitation radiation into a medium (8) under investigation and the coupling of the electromagnetic radiation scattered by the medium (8) under investigation into a spectral optic system (10), a laser diode (1) for generating excitation radiation with at least two different wavelengths (λ1, λ2) being controlled with at least two different excitation conditions and at least one Raman spectrum (16, 17) being detected in each case from the scattered radiation at the different excitation wavelengths (λ1, λ2), and the Raman spectrum (20) of the medium (8) under investigation being determined from the at least two detected Raman spectra (16, 17), the two different excitation conditions for the laser diode (1) being adjusted by means of the electric current supplied to the laser diode (1).
