Lasers for Raman Spectroscopy

The Indian physicist C.V. Raman was awarded the 1930 Nobel prize in physics for his discovery of "Raman Effect" and his systematic exploration of it. This discovery opened the door of Raman spectroscopy.  Raman spectroscopy is a spectroscopic technique used to determine vibrational modes of molecules. It is based onRaman scattering ofmonochromaticlight, usually from a laser in thevisible,near infrared, ornear ultraviolet range, and it shows 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, and a high level of wavelength stability.

 


360nm Laser for Raman
Narrow spectral bandwidth, good wavelength and power stability, visible beam spot, strong Raman signal.

 

405nm Laser for Raman
Narrow spectral bandwidth, good wavelength and power stability, visible beam spot, strong Raman signal.

 

532nm Laser for Raman

 

785nm Laser for Raman
Narrow spectral bandwidth, good wavelength and power stability, avoiding the fluorescence wavelength range.

 

1064nm Laser for Raman
