This high-pulse-frequency laser light source will be used to study pulp fibre motion in various pulp and paper industrial processes (refining, screening, sheet forming). The results of these studies will be used to improve the efficiency and quality of these papermaking operations. The light source will also be used to study spray behaviour, specifically the impaction of sprays onto a moving surface and the shot-to-shot variability in sprays generated by a fuel injector. The former application is relevant to understanding the deposition of friction modifying agent onto railroad tracks. The latter application is central to developing a superior fuel injection nozzle for combined diesel-natural gas fueled vehicles.

这种高脉冲频率激光光源将用于研究各种纸浆和造纸工业过程（精制，筛选，纸张成形）中的纸浆纤维运动。这些研究的结果将用于提高这些造纸操作的效率和质量。该光源还将用于研究喷雾行为，特别是喷雾对移动表面的冲击和喷油器产生的喷雾的喷射变化。前一个应用与理解摩擦改性剂在铁路轨道上的沉积有关。后一种应用对于开发用于组合的柴油-天然气燃料车辆的上级燃料喷射喷嘴至关重要。
