We present what we believe to be the first demonstration of spectral combining of multiple fiber lasers Q-switched by independent micro-electro-mechanical system (MEMS). By correlating the actuation of the individual MEMS devices, the associated Q-switched lasers can be operated in either synchronous or asynchronous modes in such a way that their overall combined output may result in high energy emission pulses or in laser emission with higher pulse repetition rate. In a proof-of-principle experiment, we demonstrate the combination of four individual Q-switched lasers (each of them operating at 20 kHz repetition rate) leading to a final laser system generating pulses with a repetition rate of 80 kHz.
我们展示了我们认为是首次通过独立微机电系统（MEMS）对多个调Q光纤激光器进行光谱合成的演示。通过关联各个MEMS器件的驱动，相关的调Q激光器可以同步或异步模式运行，使得它们的整体合成输出可能产生高能量发射脉冲或具有更高脉冲重复率的激光发射。在原理验证实验中，我们展示了四个独立调Q激光器（每个激光器的重复频率为20kHz）的合成，最终得到了一个重复频率为80kHz的脉冲激光系统。
