Abstract
A method of manufacturing a solid-state material comprises a first step of preparing a starting material having an energy-level structure with at least first, second and third energy levels, each having a specific level width, the first energy level is the lowest of the three levels, one of the second and third energy levels changing the energy-level structure when light having a predetermined wavelength is applied to the material, and the energy-level structure remaining so changed even after the application of the light, and a second step of irradiating the starting material with a first coherent light beam resonating with transition between the first and third energy levels and a second coherent light beam resonating with transition between the second and third energy levels in a case that the third level is a level which changes the energy level structure, thereby changing a distribution of angular frequency in a plane one axis of which is a first transition angular frequency corresponding to the transition between the first and third energy levels and the other axis of which is a second transition angular frequency corresponding to the transition between the second and third e…
