Compact Low-energy High-repetition Rate Laser-induced Breakdown Spectroscopy for Lead Element Detection
A compact laser-induced breakdown spectroscopy using a low-energy, high-repetition rate Nd: YAG DPSS laser as excitation source has been developed. The influences of laser repetition rate and laser power on LIBS signal were analyzed. When the laser operated at 4 kHz, pulse energy of 745 μJ and pulse width of 17 ns, the seven emission lines of Lead (Pb) was obtained. Compared with the traditional single pulse LIBS, the number of emission lines is increase, also the signal-to-noise ratio is improved by almost 73%. Based on simplified setup and low energy, high-repetition rate laser-induced breakdown spectroscopy will be applied in more emerging fields.
