    "abstract": "The near-field diffraction of fs and sub-fs light pulses by nm-size slit-type\napertures and its implication for near-field scanning optical microscopy (NSOM)\nis analyzed. The amplitude distributions of the diffracted wave-packets having\nthe central wavelengths in the visible spectral region are found by using the\nNeerhoff and Mur coupled integral equations, which are solved numerically for\neach Fourier\u0027s component of the wave-packet. In the case of fs pulses, the\nduration and transverse dimensions of the diffracted pulse remain practically\nthe same as that of the input pulse. This demonstrates feasibility of the NSOM\nin which a fs pulse is used to provide the fs temporal resolution together with\nnm-scale spatial resolution. In the sub-fs domain, the Fourier spectrum of the\ntransmitted pulse experiences a considerable narrowing that leads to the\nincrease of the pulse duration in a few times. This imposes a limit on the\nsimultaneous resolutions in time and space.",
