In this work,we take direct image of plasmon on tips of the nanoprisms in bowtie nanostructure excited by 7 fs laser pulses and coherent control of the ultrafast plasmon near field distribution in the vicinity of bowtie nanostructure by changing the phase difference between the orthogonal incident light with photoemission electron microscopy (PEEM) and further probe the ultrafast plasmon dynamics by combining the pump-probe technology with three-photon PEEM and obtain a series of images of local surface plasmon modes evolution on different tips of the bowtie.
