【摘要】 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。更多还原

【Abstract】 This paper deals with the threshold condition of double resonance parametric oscillation when the absorption coefficient of the signal light is different from that of the idling light. A general expression of threshold condition was obtained and discussed. The result becomes that of the widely accepted theory when the absorption coefficient of the signal light is the same with that of the idling light, therefore the threshold condition in this paper is universal.更多还原
