Abstract

The Raman band of Nd:YAG laser second-harmonic scattering from the O-H stretching vibrations of hexagonal ice was observed to broaden asymmetrically by 90 cm−1 near 0°C with the pulse repetition frequency increasing from 1 to 8 Hz. The center of this band was found to undergo simultaneously a Stokes shift by 25 cm−1. The observed spectral features can be accounted for by the ice being heated by pulsed laser radiation through the electrocaloric effect, because the one-photon absorption mechanism produces a negligible contribution.
