摘要：

The propagation of the slow shear wave in paratellurite with an angular tilt theta from the [110] axis in the (001) plane is considered. Original formulations are given for the acoustic velocity, the power flow angle, and the acoustic divergence. For a small angular deviation, the acoustic spreading is greatly reduced. This configuration can be used for multichannel Bragg cells. In order to demonstrate the feasibility of such a device, a three-channel Bragg cell (theta=5 degrees) has been designed and successfully tested. (C) 1998 American Institute of Physics.
