受激布里渊散射相位共轭现象的二维数值模拟

TWO-DIMENSIONAL NUMERICAL CALCULATION OF THE OPTICAL PHASE CONJUGATION IN STIMULATED BRILLOUIN SCATTERING

使用Ｐ．Ｈ．Ｈｕ等人［３，４］提出的计算途径，数值解了Ａ．Ｆｌｕｓｂｅｒｇ等人［２］提出的零级方程．计算了布里渊池内随位置而变化的斯托克斯光强度、泵浦光强度和保真度，得到了布里渊池内几个位置上的斯托克斯光相位和强度的横向分布，并计算了泵浦光入口处的反射率和保真度。

Using the calculation way suggested by P.H.Hu et al.we solve the zeroth-order equations suggested by A.Flusberg et al in numerical method.We calculate the Stokes intensity,the pump intensity,and the fidelity that vary with the positions in the Brillouin cell,and obtain the transverse distributions for the Stokes phase and intensity at several positions in the Brillouin cell,and calculate the reflectivety and fidelity at the pump entrance that vary with the gain G=gI L.
