Combining femtosecond time-resolved spectroscopy and scanning near-field optical microscopy (SNOM),we can obtain the spectra with ultrahigh temporal and spatial resolutions simultaneously. Some problems in doing so are discussed. Then we show the important applications of the ultrahigh spatiotemporal resolved spectroscopy with a few typical examples.展开更多
