Laser induced discharge reinforcement plasma spectrum detection device

The invention belongs to the technical field of plasma spectrum detection, in particular to a laser induced discharge reinforcement plasma spectrum detection device. The laser induced discharge reinforcement plasma spectrum detection device comprises an incidence unit, a signal reception unit, an object carrying platform and a data analysis unit, wherein the incidence unit comprises a YAG laser and a lens, and the signal reception unit comprises a probe, an optical fibre and a spectrograph. The laser induced discharge reinforcement plasma spectrum detection device is characterized in that the plasma detection device is provided with a signal reinforcement unit which comprises a high-voltage quick-discharge loop. The invention not only inherits various advantages of the traditional LIBS technique but also has the characteristics of stronger signal intensity, lower sample detection limit, higher stability and the like; compared with a DP-LIBS technique and an LIBS-LIF technique, the invention has simple equipment of a detection system, easy operation, lower cost and better practicability.
