Change of dominant material properties in laser perforation process with high-energy lasers up to 120 kilowatt

open access: yesScientific Reports, 2023
In laser materials processing, energy losses due to reflection, heat conduction and thermal radiation play an important role. In this publication, we show that with increasing laser intensity, the energy lost within the sample becomes less important for ...

Continuous wave high-power laser propagation in water is affected by strong thermal lensing and thermal blooming already at short distances

open access: yesScientific Reports, 2021
When laser beams propagate through media with non-vanishing absorption, the media is heated resulting in a change of the refractive index, which can lead to thermal lensing and thermal blooming.
