| Abstract: | The mercurous chloridc (Hg2Cl2) single crystal possesses unique acousto-optic (AO)properties, which make Hg2Cl2 Bragg cells desirable for various optical signal processing applications. Based on the design theory of beam stcering birefringent device, in this paper it is presented to design parameters of Hg2Cl2 devices. The performances of this new-type devices are also analyzed. The results show that, the sizes of Hg2Cl2 devices are much smaller than those of TeO2 devices, along with other good performances. Due to these advantages, the Hg2Cl2 Bragg cells can be expected to be keydevices in two-dimensional AO signal processing systems. |
