Description
Evaldas Kažukauskas's team explains ripples during ultrafast laser deep carving, in a 2026 study. High, wide-spaced surface ripples raise roughness and defeat control during deep carving of glass-like solids, limiting the technique. The team mapped the conditions under which ripples form and how they depend on machine settings.
A math model of sound waves in a tight cavity, combined with experiments, showed ripples arise from the mix between incoming laser pulses and leftover effects of prior pulses. Building on that insight, the team devised fixes that cut final surface roughness tenfold. The work makes deep laser carving tamer for fine work.
