Abstract: In the control of light condensing irradiation of laser light using a spatial light modulator, the number of wavelengths of the laser light, a value of each wavelength, and incident conditions of the laser light are acquired (step S101), 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 (S104), and a light condensing control pattern to be provided for the laser light is set for each light condensing point (S107). Then, a modulation pattern to be presented in the spatial light modulator is designed in consideration of the light condensing control pattern (S108). 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 on the light condensing point, a propagation function to which a phase pattern opposite to the light condensing control pattern is added is used. Thereby, a light modulation control method, a program, a device, and a laser light irradiation device, which are capable of preferably achieving light condensing control of laser light are achieved.
