说明：  修正BBO晶体折射率色散公式中错误的系数 ，完成βBBO晶体Ⅱ类匹配的SPDC（共线情况）并计算相位匹配角。此时的相位匹配角为能 产生纠缠光子对的最小切割角。另附一份参考文献，详细的说明此类实验的步骤与细节。(Correct the wrong coefficient in the refractive index dispersion formula of BBO crystal, complete the type II matching SPDC of BBO crystal and calculate the phase matching angle. The phase matching angle is the minimum cutting angle that can produce entangled photon pairs. In addition, a reference is attached to explain the steps and details of such experiments in detail.)
