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. Express24, 25718 (2016)OPEXFF1094-408710.1364/OE.24.025718 and Fernandez J. Phys. D48, 155101 (2015)JPAPBE0022-372710.1088/0022-3727/48/15/155101 suggest that the distribution of the generated plasma during writing is responsible for the newly revealed phenomena.
