Abstract
This paper investigates the optimization of double-pulse collinear femtosecond laser-induced breakdown spectroscopy (FLIBS) for silicon. Double-pulse FLIBS signal enhancements were observed over an extended range of sample focal plane position compared to single pulse FLIBS. The FLIBS signal intensity was studied as a function of pulse energy, inter-pulse delay (0 ps-80 ps) and sample position. Correlation between crater volume and signal intensity was measured over a limited range of the sample focal plane position. It was found that double-pulse FLIBS is superior to single pulse for certain focal plane positions.
