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。
Four channels of 500Wpower-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 Woutput 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.
