论文摘要
在这项工作中,我们研究了具有固有振幅噪声抑制机制的非线性扩增环形摩擦型纤维激光器模式的稳态。由于正弦传递函数与波动的腔内脉冲振幅的相互作用,我们表明,在特定前提条件下,这种机制可能导致反射和传输输出端口处的相对强度噪声的可检测差异。我们使用基于非线性纤维的系统进行系统的强度噪声测量,该系统复制激光腔中的单个往返。实验结果和模拟清楚地表明,对于某些稳态,驱动内振幅波动的减少高达4 dB。
In this work, we investigate the steady-states of a fiber lasers mode-locked with a nonlinear amplifying loop-mirror that has an inherent amplitude noise-suppression mechanism. Due to the interaction of the sinusoidal transmission function with the fluctuating intracavity pulse amplitude we show that this mechanism may lead to a detectable difference in relative intensity noise at the reflected and transmitted output port under specific preconditions. We present systematic intensity noise measurements with a nonlinear fiber-based system that replicates a single roundtrip in the laser cavity. Experimental results and simulations clearly show a reduction of the intracavity amplitude fluctuations up to 4 dB for certain steady-states.
