Abstract

Provided in the invention is an improved illumination light control method. The method comprises: an irradiation condition obtaining step; to be specific, obtaining and using an incident pattern of laser to a spatial light modulator, a first refractive index n1 of a first propagation medium on a propagation path of the laser from the spatial light modulator to a focus point, and a second refractive index n2, different from the first refractive index, of a second propagation medium closer to the focus point side than the first propagation medium as laser irradiation conditions; and a light condensation condition setting steps; to be specific, setting the number st of condensation points for condensed irradiation on the laser from the spatial light modulator as well as respective condensation positions and condensation strength of the st condensation points as the condensation conditions of the laser. The st is an integer larger than 1.

Description

technical field [0001] In particular, the present invention relates to an improved illumination light control method. Background technique [0002] In recent years, research on optical integrated circuits, such as waveguides, optical splitters, and directional couplers, etc., has been fabricated three-dimensionally inside glass. As one of the methods of manufacturing such an optical integrated circuit, there is a method using a femtosecond laser. In this method, for example, by inducing impact at the converging point of the femtosecond laser light by two-photon absorption or the like, it is possible to locally change the refractive index of the glass. In addition, such focused irradiation of laser light on an irradiation object is widely used in various laser processing devices or laser microscopes for observing the scattering and reflection of laser light in addition to the production of optical integrated circuits. When a single laser beam emitted from a laser light sour...
