Abstract
A light illumination device, a light processing apparatus using the light illumination device, a light illumination method, and a light processing method. The light illumination device, the light illumination method, and the light processing method include converting a phase distribution of a transmitted wavefront of light emitted from a light source, changing a ratio between a first diameter of a cross section perpendicular to an optical axis of the light whose phase distribution of the transmitted wavefront is converted in the converting along a first axis and a second diameter along a second axis perpendicular to the first axis and the optical axis of the light, and condensing the light whose ratio between the first diameter and the second diameter is changed in the changing.
