本文报道了一种利用偏振相关耗散孤子强度调制效应的瓦级、重复率可切换的全光纤啁啾脉冲放大系统。通过偏振识别装置（即偏振器）和偏振旋转矢量孤子（PRVS）的组合实现脉冲重复率调谐的强度调制。通过调节注入偏振器的耗散孤子偏振态，获得了约100%的强度调制深度，周期为两次空腔往返。基于这一机制，CPA系统输出脉冲的重复频率可以在1.37 MHz和2.74 MHz之间动态切换。在1.37 MHz和2.74 MHz的重复频率下，脉冲能量分别为~2.0 μJ和~2.2 μJ，对应脉冲持续时间分别为1.12 ps和970 fs。这些发现将为高功率激光系统中脉冲重复率的动态调谐提供一种替代方法，也支持了矢量耗散孤子基础研究在柔性高能脉冲激光系统等实际应用中的意义。
We report a watt-level, repetition-rate-switchable all-fiber chirped pulse amplification (CPA) system by using polarization-dependent dissipative soliton intensity modulation effect. The intensity modulation for pulse repetition rate tuning is realized by combination of the polarization discrimination device (i.e., polarizer) and the polarization-rotating vector soliton (PRVS). Up to ~100% intensity modulation depth with a period of two cavity roundtrips for the PRVS seed was obtained by adjusting the dissipative soliton polarization state that was injected into the polarizer. Relying on this mechanism, the repetition rate of the output pulse from the CPA system can be dynamically switched between 1.37 MHz and 2.74 MHz. The pulse energy of ~2.0 μJ and ~2.2 μJ were achieved for the repetition rates of 1.37 MHz and 2.74 MHz, corresponding to 1.12 ps and 970 fs pulse duration, respectively. These findings would provide an alternative method for dynamic tuning of pulse repetition rate in high power laser systems, which also underpins the significance of fundamental research of vector dissipative solitons in practical applications such as flexible high-energy pulse laser systems.
