The presented review summarizes nearly two decades studies on femtosecond laser induced breakdown spectrometry (fs-LIBS). When ultra-short (<1 ps) laser pulse is used for ablation the physics of laser induced plasma changes dramatically in comparison with ablation by pico- or nanosecond pulses. Femtosecond laser pulse interacts only with electron subsystem while nanosecond pulses continuously interacts with different thermodynamic states of material starting from solid through liquid into plasma. Properties of ultra-short laser radiation, timescale of fs-laser ablation and radiative properties of fs plasma are briefly described. We consider the advantages of fs-LIBS, namely low ablation thresholds, high-spatial resolution, rapid analysis of samples, which require minimal invasion, high-efficiency transportation of laser radiation under filamentation mode for remote analysis. Also we discussed possible limitations of this technique and different approaches to overcome such constraints keeping unique possibilities of fs-LIBS.
