我们报告了当纳秒拉曼激光器腔的往返时间与纵向多模泵浦激光器的往返时间匹配或与后者以小整数的比率相关时，纳秒拉曼激光器的产生阈值局部降低和输出能量增强的观察结果。我们将这两个观察结果都称为同步泵浦效应，该效应源自泵浦脉冲的小尺度强度结构的周期性。
We report on the observation of local reduction in generation threshold and enhancement in the output energy of a nanosecond Raman laser when the round-trip time of its cavity is matched with that of a longitudinally multimode pump laser or related to the latter as a ratio of small integers. We refer both observations to the synchronous pump effect originating from the periodicity in the small-scale intensity structure of the pump pulse.
