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

Scientific 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.
