Abstract

The spectral bands shape of sea water Raman scattering and laser induced fluorescence of chlorophyll A were experimentally investigated when scattering and fluorescence induced by the different wavelength and duration of laser radiation. The femtosecond laser pulses with 400, 480, 500 nm of wavelength, nanosecond impulse (532 nm) and continuous laser radiation (527 nm and 400 nm) were used in these experiments. The spectral line shape of the sea water Raman scattering is Gauss function corresponding to the symmetrical vibrations (ν₁) when femtosecond laser pulses were used. Maxima corresponding to the Fermi resonance (2ν₂) and antisymmetric vibrations (ν₃) were not detected.
