Abstract: A handheld LIBS device and method includes a laser assembly producing two pulsed single spatial mode output beams and a focusing optic which combines the two pulsed single spatial mode output beams at a focal point at a sample. The laser assembly includes a laser assembly housing with an output coupler window for the two pulsed single spatial mode output beams, a gain medium in the laser assembly housing between the output coupler window and an adjustable prism mount in the laser assembly housing holding a prism configured to establish two light paths through the gain medium, a source in the laser assembly housing providing pump energy to the gain medium, and a Q-switch positioned between the prism and the gain medium.
