Lasers for Raman Spectroscopy

Raman spectroscopy is a spectroscopic technique used to determine vibrational modes of molecules. Based on Raman scattering of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range, it is able to show the spectrum for the materials characteristic and identification. Used for jewelry appraisal, forensic appraisal and other materials, Raman spectrum solution requires lasers with narrow spectral bandwidth, high spectral purity, high level of wavelength stability and high efficiency. As a general guide, laser sources at the ultraviolet wavelength range are ideal for resonance Raman on bio-molecules, such as proteins, DNA and RNA, fluorescence suppression. Laser sources at the visible range are perfect for inorganic materials and resonance Raman experiments (e.g., for carbon nanotubes and other carbon materials) and surface enhanced Raman scattering (SERS). Near-infrared laser sources are ideal for fluorescence suppression and high output power. Two-wavelength laser source for Raman Spectroscopy may be available upon request.

To guarantee the stability and accuracy of the Raman testing results, Lasermate Group, Inc. provides different laser sources specifically designed for Raman spectroscopy applications at different kinds of wavelengths and power levels to meet customer's practical requirements.
