Abstract

A spatio-temporal focusing technique can be used to enhance the peak intensity in filamentation [Phys. Rev. A 84, 063819 (2011)]. We experimentally applied this technique to remote filament-induced breakdown spectroscopy. Significant enhancement of the fluorescence signals was achieved on iron and aluminum samples from 22 m away using spatio-temporally chirped pulses when compared with using normally compressed pulses.
