laser
have been utilized in the Raman spectrophotometers [9, 11]. The argon-ion and
krypton ion light sources are short-wavelength sources that can produce significant
fluorescence. However, diode or Nd: YAG lasers are long-wavelength light sources
and can be operated at much higher power without causing photodecomposition of
sample and eliminates or reduces fluorescence in most cases [14].
