In this work, we present a double pulse LIBS system utilizing modified commercially available Laser Ablation System (New Wave, UP 266 MACRO), second Nd:YAG laser (Quantel, Brilliant) and a unique combination of ICCD and PMT detection. It was shown that combination of these two detectors in one experimental setup can be useful to determine both, the spectral and time resolved plasma emission. Preliminary measurements with this setup were focused on determination of the plasma temperature in different time intervals after the first laser pulse reaches the target. The plasma temperatures calculated from time dependent signals of iron atomic emission lines series demonstrate the advantages of this system for such type of measurements. The temporal emission signal measured by gated PMT can be useful not only for direct plasma diagnostic, but also for selecting the best ablation conditions including the optimum delay time between the two laser pulses and the delay and duration of ICCD acquisition. Moreover, in case of complicated samples the gated PMT can help to discover the matrix effect or spectral interferences. The aim of this reliability study was to proof the potentialities of the developed instrumentation. On the frame of the ongoing work more detailed study of the influence of double pulse conditions on the laser induced plasma properties and application of this technique for different samples are planned.
