Raman Laser

Spectrecology 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.

The 532 nm wavelength option is a workhorse for inorganic materials, offering maximum signal for samples that do not suffer from autofluorescence. Also, 532 nm is useful for Raman resonance experiments and for the study of carbon materials including carbon nanotubes and fullerenes.

The most popular Raman excitation wavelength is 785 nm. Raman 785 nm systems yield excellent quality Raman spectra for most chemicals, with limited interference from fluorescence. These systems also offer very good spectral resolution, making 785 nm Raman excitation an excellent choice for the measurement of chemicals and organic materials.
