Method of detecting steel sample components using multi-pulse laser induced plasma spectrum analyzer

摘要

A method of detecting steel sample components by using a multi-pulse laser-induced plasma spectrum analyzer. The present invention employs a multi-pulse laser-induced plasma spectrum analyzer to detect steel sample components, particularly a multi-pulse laser-induced plasma spectrum analyzer including picosecond and nanosecond laser pulse widths. Regarding the method of detecting steel sample components, the laser-induced light source is a laser light source including ultra-short pulses of nanosecond order and picosecond order, and one pulse laser and two pulse lasers, nanosecond laser and picosecond laser. The two lasers can be focused at the same position on the sample to be detected by the same power and focusing optical path, and the first nanosecond laser pulse is used to illuminate the surface of the sample to generate a plasma. Then, plasma is irradiated using the second picosecond laser pulse to To reinforce the torque line firing. [Selection] Figure 1
