What are Raman Spectroscopy Lasers?

Raman spectroscopy lasers are typically wavelength stabilized volume Bragg grating (VBG) laser diodes or single-frequency DPSS lasers, which allows for accurate wavelength shift (Raman shift) measurements, critical to Raman Spectroscopy.

So, What is Raman Spectroscopy?

Raman Spectroscopy is an analytical technique, studying the vibrational modes of molecules, used to identify and quantify the chemical composition and molecular bond structure of a sample by the analysis of scattered light.

Raman spectroscopy is a vibrational spectroscopy technique unique from other vibrational spectroscopy techniques in that it can non-destructively measure samples in real time with no or very little sample prep. 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 (i.e., measuring the vibrations of molecular bonds). 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.
