Abstract

Resonant Brillouin scattering by the transverse acoustic phonons is investigated for the first time in red HgI~2~ single crystal at room temperature by using the acoustic domain injection method. The measured results in the spectral region 579 to 800 nm show a non‐dispersive feature at the longer wavelength region and a decrease in the region very close to the fundamental absorption edge. The analysis based on the resonant Brillouin scattering theory and piezobirefringence theory shows excellent agreement with the present observation and predicts a resonant cancellation of the scattering cross section at 574 nm.

The acoustic properties of PMMA poly(methyl methacrylate) deformed by tensile stress were investigated by the coherent Brillouin scattering method. The ultrasonic velocities of PMMA in steady stress-strain states were measured in the frequency range of 100 MHz to 1 GHz. The ultrasonic velocities dec
