It is known that the large number of photons generated at each pump shots leads to a deterioration of the visibility with respect to the coincidence (low gain) regime because of the appearance of a high background level which tends to hide the imaging information. However it will be shown that such a drawback can be fully compensated by performing spatial averages on the single pump shot in addition to temporal averages on different shots.","PeriodicalId":179542,"journal":{"name":"EQEC '05.

A grazing incidence illumination configurations adopted, with excitation of the tip dipole along its axis, and backscattering collection arrangement along the maximum emission direction. This optimized geometry resulted in a 2/3 orders of magnitude increase of the efficiency (up to 10/sup 6/ photons/s) with respect to previous experiments, allowing standard scan rates for NSOM imaging. An extended-cavity Ti:sapphire oscillator is developed that generates 25-fs pulses at 800 nm with 25 MHz repetition rate, obtaining a fourfold increase in pulse energy at given average power, minimizing thermal effects on the tip.","PeriodicalId":179542,"journal":{"name":"EQEC '05.
