Introduction

Laser-induced breakdown spectroscopy (LIBS) technology, as an atomic emission spectrometry technology, has many advantages such as fast detection speed, no need for sample pre-processing, and the ability to perform in-site real-time detection. It has been widely used in metallurgy, environmental protection, geology, mining, biomedicine and other fields. This experiment is designed as an open system. Through the construction of the system, students can freely control core devices such as lasers, focusing mirrors, coupling mirrors, and spectrometers to detect the spectra of various alloy samples and analyze the elemental composition of the samples.
