The mechanisms of laser-induced modification of transparent materials are complex combinations of different processes that depend on the material itself and a range of processing parameters. As such, the mechanisms are still subject to ongoing study. We use a custom-built adaptive third-harmonic generation (THG) microscope to study those mechanisms. New femtosecond-laser-written phenomena are revealed through this method of imaging. This Letter, together with previous reports by Miyamoto Opt. Express 24, 25718 (2016) [CrossRef] and Fernandez J. Phys. D 48, 155101 (2015) [CrossRef] suggest that the distribution of the generated plasma during writing is responsible for the newly revealed phenomena.

三次谐波显微镜研究激光写入波导形成的结构机理

激光诱导的透明材料改性的机制是取决于材料本身和一系列加工参数的不同过程的复杂组合。因此,该机制仍在继续研究中。我们使用定制的自适应三次谐波生成(THG)显微镜来研究这些机制。通过这种成像方法可以发现新的飞秒激光写入现象。本信以及宫本优化的先前报告。快递24,25718(2016)[交叉引用] 和费尔南德斯J.物理学。d 48,155101(2015)[交叉引用] 表明,所产生的等离子体的写入期间的分配负责新发现的现象。
