We perform the in situ characterization, by second-order optical autocorrelation, of femtosecond pulses transmitted by near-field optical probes. We demonstrate that transmission through hollow pyramid probes with diameter down to 65 nm has negligible effects on the duration of pulses as short as 30 fs. We also show that such probes allow obtaining, at their output, sufficient peak power to perform nonlinear optical experiments in the near field on such a space and time scale.

Abstract

We perform the in situ characterization, by second-order optical autocorrelation, of femtosecond pulses transmitted by near-field optical probes. We demonstrate that transmission through hollow pyramid probes with diameter down to 65 nm has negligible effects on the duration of pulses as short as 30 fs. We also show that such probes allow obtaining, at their output, sufficient peak power to perform nonlinear optical experiments in the near field on such a space and time scale.
