Laser diodes for Raman spectroscopy

Commonly used in chemistry to provide a fingerprint by which molecules can be identified, Raman Spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. It relies on inelastic or Raman scattering of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range. The laser light interacts with molecular vibrations, phonons or other excitations in the system, resulting in the energy of the laser photons being shifted up or down. The shift in energy gives information about the vibrational modes in the system. Infrared spectroscopy yields similar, but complementary, information.

Electro Optical Components has a variety of laser diode modules specifically for Raman Spectroscopy.

The 785, 830 and 1064 nm lasers are narrow bandwidth for precision in the Raman Spectroscopy process.

One package combines the 785 and 1064 nm lasers so you can switch to the one that suits your application the best.

All lasers (leaded package) require a driver, but many users have or want to design their own driver. If you need a driver for the laser (not laser system) let us know and we will include this.

Compact Raman Laser – Wavelength Stabilized

Electro Optical Component’s Compact Raman Laser offers the same narrow spectral width and wavelength stabilization as the bigger modules, but they are much smaller for Raman applications where size is an issue.
