| 摘 要： | 基于主动锁相相干偏振合成系统实现了四路500 W级全光纤窄线宽保偏放大器的共孔径合成输出。当相位控制系统处于闭环状态时, 整个合成系统的输出功率达2164 W, 合成效率为94.5%。实验中, 随着功率的提升, 合成效率未发生明显退化。这是目前相干偏振合成系统的最高输出功率。

| Abstract: | Four channels of 500 W power-level all fiberized, narrow-band, and polarization-maintained amplifiers are coaxially combined using active phasing coherent polarization beam combining (CPBC) system. When the phase control system is in closed loop, 2164 W output power is achieved with combing efficiency of 94.5%. In the experiment, the combining efficiency does not degrade obviously along with power scaling process. This is the highest output power based on CPBC system up to now. |
