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. Dual 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.
