Abstract
A first optical modulation element irradiates a non-single-crystal substance with a light beam which is to have a first light intensity distribution on the non-single crystal substance by modulating an intensity of an incident first light beam, thereby melting the substance. A second optical modulation element irradiates the substance with a light beam which is to have a second light intensity distribution on the substance by modulating an intensity of an incident second light beam, thereby melting the substance. An illumination system causes the light beam having the second light intensity distribution to enter the molten part of the substance in a period that the substance is partially molten by irradiation of the light beam having the first light intensity distribution.
