Sealed laser induced breakdown spectroscopic sensing system and applications thereof

Abstract

A system and a method for spectroscopic sensing are provided for chemical and molecular species detections and trace concentration measurements as a standalone unit. The system may include a laser module configured for producing a laser beam capable of creating a plasma plume of a sample, the laser module comprising a Nd:YAG rod and diode lasers that are placed radially surrounding the Nd:YAG rod, wherein the diode lasers are configured to generate light having a spectral band width that overlaps absorption bands of Nd; a detector module configured for identifying elemental and trace chemicals from the plasma plume; and a computing module configured to acquire, store, and/or output data from the detector module. The disclosed system may be tightly sealed in a metal housing suitable for field applications in harsh environments for long durations, such as in subsurface conditions, in a high pressure and high temperature, or underwater.
