Abstract:
By using a high-precision FM Brillouin spectrometer with the spectral resolution of 20 kHz, we have succeeded in determining the Brillouin linewidth of single-crystal LiTaO(3). The large directional anisotropy for the attenuation rate of the longitudinal elastic wave and the extremely narrow Brillouin linewidth of 1.60 MHz have been observed at room temperature.
