Abstract
A substrateincludes a color center excited by excitation light, and at least a pair of reflection membersare arranged with gaps from the substrate. The substratecauses the excitation light entering the substrateto exit through its surfaces without reflection, and the reflection memberscause the exited excitation light to reflect at the reflection surface-or-and enter the substrate, and cause the excitation light to repeatedly enter and exit the substrateand thereby pass through the substrateonly a predetermined number of times. Here, the irradiating deviceemits the excitation light such that the excitation light is incident to the reflection surface-or-with an angle perpendicular to one axis among two axes of the reflection surface-or-and with a predetermined slant angle from the other axis.
