Ocean Optics offers high power lasers for Raman excitation wavelengths of 532, 638, 785 and 1064 nm. These multimode diode lasers produce narrow spectral lines, have integrated laser drivers and are thermoelectrically cooled for optimum performance. Options are available with adjustable output power and with SMA 905 or FC fiber connections.

 

  • Integrated laser package – turnkey solution with integrated laser drive, TEC cooled electronics and safety switches
  • Multiple options – available in 532, 638, 785 nm and 1064 nm Raman excitation wavelengths
  • Adjustable output power – options for manual or remote control of laser drive current

 

Raman lasers are available in a variety of excitation wavelengths, although 532 nm and 785 nm excitation are among the most typically specified. Excitation at 785 nm minimizes the fluorescence signal, making it useful for chemical identification and fingerprinting. Also, excitation at 785 nm generates well defined peaks for use in chemometric analysis and can provide semi-quantitative data.

For applications where C-OH structural information is important, laser excitation at 532 nm is a good option. Such measurements are typical of biological and pharmaceutical sample analysis, where researchers study characteristics of active ingredients, binders, fillers, lubricants and excipients.

Ocean Optics offers high-power 785 nm laser subsystems for Raman applications where integrating the laser into the system setup is desirable. These OEM laser packages are distinguished by high output power, narrow spectral bandwidth and great stability. Each unit’s stabilized peak wavelength remains locked regardless of case temperature (-10 °C to 55 °C).

Raman laser subsystems include an integrated laser drive and temperature-controlled electronics and can be spectrally tailored to suit application needs. The units have side mode suppression ratios better than 40 dB, which provides extremely high signal-to-noise ratio performance for Raman spectroscopy and pump laser applications.

 
  • Multimode laser package – ideal for integrating into other devices for Raman spectroscopy
  • Great stability – integrated laser driver and TEC controller
