The discovery and understanding of many ultrafast dynamical processes are often invaluable. This paper is the first report to apply optical parametric amplification to implement single-shot ultrafast imaging with high space and time resolutions. Our setup breaks the constraints usually occurring among the time resolution, frame number, frame interval and spatial resolution in existing single-shot femtosecond imagers, so its performance can be greatly improved by using laser pulses with higher power and shorter time durations. Our setup has provided the highest experimental record of the frame rate and spatial resolution with the temporal resolution of 50 fs simultaneously. It is very powerful for accurate temporal and spatial observations of the ultrafast transient events with a lifetime down to the femtosecond scale, such as atomic or molecular dynamics in photonic material, plasma physics, living cells, and neural activity.

All-optical switching via coherent control of plasmon resonances
基于量子光学中\textit{Enhancement of Index of Refraction}（EIR）效应的等离子体模拟，从理论和实验上证明了一种新的超快全光开关机制。在量子光学EIR中，原子系统通过相干和量子干涉呈现出数量级更高的折射率，在其共振附近具有消失甚至负吸收。类似地，在等离子体激元诱导的EIR中，探测信号可以经历正、零或负消光，同时与由控制光束相干激发的超分子中的金属纳米棒强烈相互作用。在超颖表面形式的这种超颖分子的正方形阵列的集体响应中观察到相同的机制，以通过从正值到负值的吸收的相干控制来调制信号的振幅，而不实施增益材料或非线性过程。这种新颖的方法可用于挑战光的控制，通过施加超短脉冲与超快表面等离子体相互作用或极低强度脉冲在单光子水平的纳米级单等离子体元分子的极端水平的空间，时间和强度。该方案也为通过放大输入信号来提高光调制器和光开关的调制强度提供了一种有效的工具。
