AI Technical Summary
Existing coherent Raman spectroscopy techniques cannot simultaneously acquire broadband coherent anti-Stokes Raman spectra and broadband coherent Stokes Raman spectra.
A dual-channel supercontinuum laser generator is used to output two beams of light: one is a single-wavelength laser as the pump light, and the other is a supercontinuum laser. By combining a collimating lens, a wavelength selection structure, and a mirror, the pump light, broadband Stokes excitation light, and probe light are combined into a coherent Raman scattering excitation light. The laser spectral lines are further selected and compressed through the wavelength selection structure and the external cavity structure.
It enables the simultaneous acquisition of broadband coherent anti-Stokes Raman spectra and broadband coherent Stokes Raman spectra, improving the spectral acquisition speed and system sensitivity, and is applicable to fields such as materials science, biomedicine, environmental monitoring and food safety.
