Abstract: A laser ablation device includes: a laser irradiation part to emit a plurality of solid-state laser beams; an optical system to convert the plurality of solid-state laser beams into output light; and a stage to receive an irradiation target to be irradiated with the output light. A minor axis of the output light has a semi-super Gaussian profile of order 2 to order 2.4.
