Raman Spectroscopy Lasers

Raman Spectroscopy Lasers Overview

Raman Spectroscopy

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 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.  For more advanced Raman spectroscopy application such as stimulated Raman scattering (SRS) and coherent anti-Stokes Raman spectroscopy (CARS), short-pulsed lasers are also used due to the non-linear nature of the process.   On this page, you will find a list of all of the spectroscopy laser sources we offer include laser diodes, DPSS, and pulsed laser systems.

The LaserBoxx SLM Series is a single longitudinal mode (SLM) CW diode laser module available in wavelengths at 633nm, 785nm, and 830nm delivering ultra-narrow linewidths thanks to its excellent temperature stability and low noise current. The Oxxius proprietary, embedded firmware locks the laser on the same mode at each startup. This compact, self-contained laser module is available in turn-key or OEM versions and utilizes a proprietary alignment-free, monolithic resonator, and comes standard with a graphic user interface with remote diagnostics via USB, RS232, or direct I/O interface.




Matchbox series of compact laser diode and DPSS laser modules are available in wavelengths from 405nm thru 1064nm. Options include collimated beam or fiber-coupled output, and single-mode and multimode versions.



R series of wavelength stabilized single-mode and multimode laser diodes offer narrow wavelength spectrum in wavelengths from 633nm thru 1064nm. Package options range from components as basic as a TO-56 or 14-pin BF packaged diodes, to OEM modules including electronics, to UL/CE and IEC certified turn-key systems.
