Raman Spectroscopy Lasers

Raman spectroscopy is the study of the vibration modes of molecules through the inelastic scattering of laser light off of a sample.  In this process, the scattered photons either lose or gain energy equal to that of the molecular bond’s vibrational modes.  By measuring the shift in wavelength from the Raman spectroscopy laser wavelength (Raman shift) you can determine the bond structure of the molecule.    Therefore, these lasers must be wavelength stabilized to ensure the accuracy of your shift calculation.  This is typically achieved through the use of a volume Bragg grating-based external cavity diode laser, but single-frequency DPSS lasers are also commonly used.

RPMC has years of experience supporting Raman Spectroscopy applications, helping industry professionals select the right tool for the job.
