Abstract
A laser beam oscillated by a laser oscillator is condensed by a condenser. The condenser includes: a concave lens; a convex lens disposed at a predetermined interval from the concave lens, and disposed at a position such that aberration of a condensing point in the atmosphere is zero; and an actuator that generates an aberration at the condensing point in the atmosphere by changing the distance of the convex lens with respect to the concave lens. The actuator generates the aberration in the atmosphere such that the aberration of the condensing point is zero within a workpiece.
