This work shows the potential of a very compact, portable Laser Induced-Breakdown Spectroscopy (LIBS) system that includes low cost and compact Nd:YAG laser, intended for use in fieldwork identification of bacteria. This device allows for the generation of 2 - 4 pulses per laser shot, with a maximum energy of 120 mJ per pulse. Each pulse has a duration of 60 ns, and the total duration of the train of pulses is 180 μs. The device dimensions including the power supply are 50 × 20 × 140 cm, which indicates that can be utilized as a portable LIBS system in field conditions. The spectra captured on two different bacteria shows the capability of identification.
