Due to the nonlinear character of the laser-matter interaction, structural modifications can occur within the focal region. To reach a full control of the process, ways of controlling the deposition of the laser energy inside the material have to be unveiled. From static and time-resolved pictures of bulk-excitation of a-SiO2 and borosilicate glass, we show that particular laser temporal shapes such as picosecond sequences can better confine the energy deposition than the femtosecond sequence by reducing the propagation artifacts.enghttps://creativecommons.org/licenses/by-nc-nd/3.0/620Pump-probeTemporal shapingUltrafast laserWaveguide writingBorosilicate glassDepositionLaser excitationLaser pulsesManufacturePumping (laser)Ultrafast lasersUltrashort pulsesEnergy depositionsLaser-matter interactionsNonlinear charactersOptical functionPump probeStructural modificationsTemporal shapingWaveguide writingLaser materials processingArticleKonferenzschrift
