The instantaneous heating of distilled water by Nd:YAG laser second harmonic pulses irradiation have been found out experimentally. The measurements have been carried out in backscattering scheme and experimental Raman spectra of water molecules stretching vibrations band were approximated by Lorentz or Gauss contour by the least squares technique. The temperature shift coefficient of both the envelope contour center is (1.0 plus or minus 0.1)cm-1 and laster pulse repetition rate temperature shifts are 2 degrees/Hz for water and 4 degrees/Hz for ice. Temperature anomalies in the approximated contour width and frequency are revealed in distilled water near the phase transition points 4, 36 and 75 degrees Celsius.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
