RAMAN SCATTERING MEASUREMENT INSTRUMENT AND RAMAN SCATTERING MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To extend a wavelength range in which a sufficient intensity can be obtained, when light to be applied to a sample is obtained by performing amplification in two stages while varying a wavelength.;SOLUTION: A Raman scattering measurement instrument combines first light and second light different by wavelengths to irradiate a sample 6 and detects the first or second light of which the intensity has been modulated by Raman scattering. Wavelength variable amplification means 20 provided in first light generation means for generating the first light performs first filtering as wavelength variable filtering for incident light, first amplification as amplification for light extracted by the first filtering, second filtering as wavelength variable filtering for the light subjected to the first amplification, and second amplification as amplification for light extracted by the second filtering. Wavelengths of light extracted in the first filtering and the second filtering are varied while matching each other.;COPYRIGHT: (C)2014,JPO&INPIT
