【Key Requirements for Ultra-Low Frequency Raman Measurements】
○Spectrometer with High Resolution Grating
＞1500 lines/mm for best performance
○Ultra-Narrow Band Notch Filters
Block excitation light,transmit signals ＞10cm-3
○ASE Suppression Filter
Suppress ASE in diode laser
Suppress nearby parastic modes of gas/solid state lasers
○Wavelength Stabilixed Laser
VHG stabilized diode laser or gas/solid-state laser

【Conclusion】
○The First reported measurements of ultra-low frequency Stokes and anti-Stokes
Raman spectra with VHG filters at 785nm show clear strong signals as low as
4ccm-1 from the excitation wavelength.
○SureBolck(TM) ultra-narrow band notch filters and NoiseBlock(TM) ASE suppression
filters are currently available for all Raman wavelengths from 400nm to ＞2000nm.
