摘要
该文介绍了常用的几种泵浦耦合技术。利用增益/泵浦一体化光纤(GTWave)侧面泵浦耦合技术,采用制备的25/250 GTWave光纤搭建了重复频率10 kHz、平均功率24.59 W、单脉冲能量高达2.459 mJ及峰值功率10 kW的脉冲光纤激光器。分析了采用该光纤进一步提高输出单脉冲能量的方法。结果表明,该光纤能够实现很高的单脉冲能量输出。
Several common pump coupling technologies were introduced in this paper. A pulsed fiber laser with repetition frequency of 10 kHz, output power of 24.59 W, single pulse energy of 2.459 mJ and peak power of 10 kW was constructed with GTWave side pumped coupling technology by using the prepared 25/250 GTWave optical fibers. Moreover, a method for further increasing the single pulse energy of the output pulse by using this optical fiber is analyzed. The results show that the fiber can achieve very high single pulse energy output.
