在高重复频率超快激光器中，很少有方法能够表征脉冲间噪声。在这里，我们使用最近开发的方法，称为保真度，以确定光谱振幅和相位噪声，导致缺乏脉冲重复性和降低激光源的性能。我们目前的钛蓝宝石振荡器和再生放大器系统在不同的噪声条件下的结果。我们的实验结果得到了数值计算的支持。
There are few methods capable of characterizing pulse-to-pulse noise in high repetition rate ultrafast lasers. Here we use a recently developed method, termed fidelity, to determine the spectral amplitude and phase noise that leads to lack of pulse repeatability and degrades the performance of laser sources. We present results for a titanium sapphire oscillator and a regenerative amplifier system under different noise conditions. Our experimental results are backed by numerical calculations.
