Optical pulses with extremely short durations (less than a millionth millionth of a second) allow dynamics to be observed on fast time scales inaccessible to other techniques. Since the energy of the "ultrafast" pulse is compressed into a short time, high peak intensities can be achieved, making possible extreme interactions between light and matter. With the newly completed Queen's ultrafast laser infrastructure, we are probing and controlling condensed matter systems on the micro and nanoscale targeting three application areas.

持续时间极短（小于百万分之一秒）的光脉冲允许在其他技术无法达到的快速时间尺度上观察动态。 由于“超快”脉冲的能量被压缩到很短的时间内，因此可以实现高峰强度，从而使光和物质之间的极端相互作用成为可能。 凭借新完成的女王超快激光基础设施，我们正在探测和控制针对三个应用领域的微米和纳米级凝聚态系统。
