20.500.12556/RUL-142960 Near threshold nucleation and growth of cavitation bubbles generated with a picosecond laser The nucleation and growth of cavitation bubbles few micrometers in size in water generated by a 60 ps 515 nm fiber laser is observed and visualized near nucleation threshold. The study is performed by monitoring the plasma size, the cavitation bubble size and the emitted shock waves. The latter two aspects are supported by the Gilmore model using a Noble-Abel-stiffened-gas (NASG) equations of state. For the first time, two types of cavitation events are identified and visualized that exhibit a difference of more than two orders of magnitude in the excitation energy converted to mechanical effects with minimal change in excitation laser pulse energy. The result is localized cavitation and reduced mechanical stress on water-based media with potentially positive implications for laser treatments of biological tissue. micro cavitation bubble nucleation dual threshold shockwaves laser induced breakdown mikrokavitacija dvojni prag udarni valovi lasersko povzročen preboj true false true Angleški jezik Slovenski jezik Članek v reviji 2022-12-06 10:41:40 2022-12-06 10:41:44 2024-03-01 03:57:14 0000-00-00 00:00:00 2023 0 0 8 str.
