平均功率范围为10-1000瓦的工业超快激光器的性能取决于其波长、脉冲持续时间、总功率和重复频率。然而，尽管具有相似的特性和制造工艺，但激光器性能的可变性表明当前的指标还不够。在这里，我们引入了功率品质因数（PFM），以量化驻留在短脉冲内的功率，而不是背景光，或脉冲之间的“暗能量”。我们介绍了利用线性采样光子计数方法来量化PFM，并展示了它在PFM范围从0.9到0.995的激光器上的应用。
The performance of industrial ultrafast lasers with average power ranging from 10-1000 Watts depends on their wavelength, pulse duration, total power, and repetition rate. However, variability in laser performance, despite similar characteristics and manufacturing, indicates the current metrics are not enough. Here we introduce the power figure of merit (PFM), to quantify the power that resides within the short pulses as opposed to the background light, or ‘dark energy’ between the pulses. We introduce take advantage of linear sampling using photon counting methods to quantify PFM and demonstrate its use on lasers with PFM ranging from 0.9 to 0.995.
