Abstract

The present invention provides a nonlinear Raman spectroscopic apparatus, a microspectroscopic apparatus, and a microspectroscopic imaging apparatus. The nonlinear Raman spectroscopic apparatus includes two light sources and a pulse control section. The two light sources are each configured to emit short-pulse laser light. The pulse control section is configured to perform time-delay for the short-pulse laser light emitted from one of the light sources.

Description

technical field [0001] The present invention relates to nonlinear Raman spectroscopy equipment, microspectroscopic equipment, and microspectral imaging equipment, and more particularly, the present invention relates to multi-channel coherent anti-Stokes Raman spectroscopy using a broadband light source as a Stokes beam device of. Background technique [0002] Laser Raman spectroscopy is an analytical technique used to separate light scattered from a sample exposed to a single-wavelength laser as the pump beam. The Stokes beam or anti-Stokes beam as scattered light shows the amount of beam displacement relative to the pump beam, and this displacement is observed as a specific spectrum corresponding to the molecular vibrational mode unique to the sample substance . Therefore, along with infrared spectroscopy, Raman spectroscopy has been widely used as a spectrum in the field of molecular fingerprints to analyze / evaluate substances, perform medical diagnosis, and develop orga...
