Comprehensive Analysis of Fundamental Dynamics in Laser-Induced Breakdown of Solid Materials

Today, lasers are unavoidable in the wide range of technologies that are used in different areas such as industry and medicine, which illustrates the strong synergic relationship between basic physics and its practical application. Here, our focus of interest is laser-induced optical breakdown in the solid materials that becomes important in a wide range of industrial applications with the development of femtosecond lasers. It is shown that the effects of the laser-induced optical breakdown in solid media can be useful, but also can lead to the modification of the material’s properties and material damages. Because of that, control of this process is crucial for laser applications. In order to achieve this, it is necessary to form a theoretical model in the sense of understanding of all relevant processes and dependence on the laser’s parameters as well. We used the rate equation model to follow the process’s dynamics. We demonstrated that the laser wavelength significantly influences the outcome of the mechanisms of interest, and therefore laser induced breakdown.
