    抜粋

    The capability of Brillouin spectroscopy for diagnosis of elasticity has been investigated. Although detection of weak signal under noise is a barrier to overcome, we have shown that the stimulated scattering can be enhanced by two orders of magnitude using stimulated thermal Brillouin scattering excited at a wavelength of 1550 nm where water has a moderate absorption of 12 cm -1. While thermal lens effect might cause excess noise in a certain experimental setup, we have shown it can be circumvented by polarization modulation technique.
