A coherent Raman spectroscopy system configured for generating a spectroscopic image of a sample and includes a light source, a supercontinuum spectrum generator, a light filter assembly and a spectroscopic assembly. The light source is for emitting a pulse laser light beam, and the supercontinuum spectrum generator is for broadening a bandwidth of the pulse laser light beam. The light filter assembly is for filtering the bandwidth of the pulse laser light beam according to a predetermined bandwidth and transforming the pulse laser light beam into a coherent spectroscopic light. The sample is disposed in the spectroscopic assembly, and the spectroscopic assembly receives the coherent spectroscopic light so that the coherent spectroscopic light passes through the sample to generate the spectroscopic image of the sample. Hence, it is favorable for adjusting the central wavelength and the bandwidth of the pulse laser light beam and the stability of measuring the sample can be improved. |
