在信号光和闲置光吸收系数不同的情况下对双谐振参量振荡阈值条件进行了分析。导出了阈值条件的一般表达式，并进行了讨论。在信号光和闲置光吸收系数相同的情况下，所得结果就退化为以前的理论结果。此阈值条件具有普遍意义。
Under the condition of different signal light and idle light absorption coefficient, the threshold conditions of dual-resonance parametric oscillation are analyzed. The general expressions for the threshold conditions have been derived and discussed. When the signal light and the idle light absorption coefficient are the same, the result is degraded to the previous theoretical result. This threshold condition has universal significance.
