Abstract
In the control of light condensing irradiation of laser light using a spatial light modulator, the number of wavelengths, a value of each wavelength, and incident conditions of the laser light are acquired, the number of light condensing points, and a light condensing position, a wavelength, and a light condensing intensity on each light condensing point are set, and a distortion phase pattern provided in an optical system including the spatial light modulator to the laser light is derived. Then, a modulation pattern presented in the spatial light modulator is designed in consideration of the distortion phase pattern. Further, in the design of a modulation pattern, a design method focusing on an effect by a phase value of one pixel is used, and when evaluating a light condensing state, a propagation function to which a distortion phase pattern is added is used.
