Features of vibroacoustic monitoring of pulsed laser operation

Today, industry is accelerating the use of laser technologies. Laser technologies are one of the areas of material machining with high-energy energy flows. This actualizes monitoring of the performance of laser technologies, because it creates the preconditions for similar research in other areas. In this article, we present the results of experiments that make it possible to determine relationships between the vibroacoustic signals accompanying the action of laser pulses on a workpiece, and the intensity and duration of individual pulses. Analysis of experimental data has lead to identification of the main mechanisms of the formation of wave processes in the workpiece exposed to laser pulses and became the foundation for assessing the role of sublimation processes. The results obtained in this work can be used to develop monitoring system of laser processing for use in automated control systems.
