ABSTRACT
This chapter presents the results of our latest studies on laser photoelectron microscopy using single-photon and selective two-step and two-photon photoionization of vari ous materials with the aid of various lasers (from CW to femtosecond types). A spatial resolution of 30-5 nm was attained in these experiments . Based on these results, a microscope with a single excitable resonance center was developed, which was proposed to be used in fluorescence resonance energy transfer (FRET) microscopy with a resolution of a few nanometers . This is essentially the further development of near-field microscopy. In addition, the results of experiments on photoion reso nance microscopy are presented, wherein a resolution of 5 nm was achieved. Con sidered in conclusion are prospects for the development of this line of rescarch as part of a new research area - nanooptics.
