ABSTRACT:
There is described a method for identifying at least one molecule in a substantially transparent medium, the method comprising: transmitting high-power, ultra-short laser pulses into the medium so as to generate filaments in which a spontaneous fluorescence signal propagating along an axis of the filament is amplified by stimulated emission; detecting the amplified spontaneous fluorescence signal; and analyzing the florescence signal to identify said molecule.
