PROBLEM TO BE SOLVED: To provide an aberration correction method by which a condensation degree of laser light can be enhanced even when a laser irradiation position in a medium is deep.;SOLUTION: The aberration correction method is applied to a laser irradiation device 1 that condenses laser light into a medium 61 having light-transmitting property. The laser irradiation device 1 includes condensing means 50 having an environmental medium 60 having a refractive index larger than that of the medium 61. A depth of a focus of the condensing means 50 from an entrance surface of the medium 61 is defined as d, assuming that a refractive index n of the medium 61 is equal to the refractive index of the environmental medium 60; and a maximum value of longitudinal aberration generated by the medium 61 is defined as Δs. Aberration of the laser light is corrected in such a manner that the condensing point of the laser light is positioned at a distance larger than n×d-Δs and smaller than n×d from the entrance surface of the medium 61, that is, the condensing point is positioned within a range where the longitudinal aberration is present in the medium when the aberration is not corrected.;COPYRIGHT: (C)2015,JPO&INPIT
