利用铜蒸气激光动力学模型模拟了注入锁定过程，分析了注入脉冲强度、宽度和延时对激光输出的影响，获得两点重要结论，即注入光出现的最佳延时与增益开始时刻相一致，注入光最佳脉宽与净增益时间宽度相一致。

Injection locking in copper vapor laser is studied numerically with a dynamic model, the effect of injected pulse power, width and delay time is calculated, and two important conclusions are obtained. One is that the optimum delay time should be consistent with the beginning of gain, the other is that the optimum pulse width should equal to the net gain width.
