通常在单色泵浦的假设下分析非简并光参量放大器的量子涨落特性。然而，在实验中，有限带宽的驱动光束被用来获得非简并信号和空闲光束放大。在此基础上，给出了有限带宽激光泵浦的非简并光学参量放大系统的解析解，并计算了相应的量子涨落。最后讨论了V1判据在两体纠缠中的应用。
Usually the quantum fluctuation characteristic of a non-degenerate optical parametric amplifier is analysed under the assumption of monochromatic pumping. However, in experiments, a driving beam with finite bandwidth is used to obtain the non-degenerate signal and idler beam amplifications. On account of that, we derive an analytical solution for the non-degenerate optical parametric amplification system with finite bandwidth laser pumping, and evaluate the associated quantum fluctuation. Finally, the application of the V1 criterion to bipartite entanglement is discussed.
