ABERRATION-CORRECTING METHOD LASER PROCESSING METHOD USING SAID ABERRATION-CORRECTING METHOD LASER IRRADIATION METHOD USING SAID ABERRATION-CORRECTING METHOD ABERRATION-CORRECTING DEVICE AND ABERRATION-CORRECTING PROGRAM
In the aberration correcting method according to the embodiment of the present invention, in the aberration correcting method of the laser irradiating apparatus 1 for condensing the laser light in the light-transmissive medium 60, the light-converging point of the laser light is generated inside the medium And the aberration of the laser light is corrected so as to be located between the aberration ranges. When the refractive index of the medium 60 is n, the depth from the incident surface of the medium 60 to the focal point of the lens 50 is d, and the aberration generated by the medium 60 is? S, And nxd or more and nxd +? S or less.
