Abstract

We theoretically demonstrate spatiotemporal control of local plasmon distribution on Au nanocrosses, which have different aspect ratios, by chirped ultra-broadband femtosecond laser pulses. We also demonstrate selective excitation of fluorescence proteins using this spatiotemporal local plasmon control technique for applications to two-photon excited fluorescence microscopy.

摘要

我们从理论上证明了通过啁啾超宽带飞秒激光脉冲对具有不同纵横比的金纳米十字上的局部等离子体分布进行时空控制。我们还展示了利用这种时空局部等离子体控制技术对荧光蛋白进行选择性激发，以应用于双光子激发荧光显微镜。
