PROBLEM TO BE SOLVED: To provide a tunable laser oscillation element using colloidal crystal gel, and to provide a manufacturing method therefor.SOLUTION: In a laser oscillation element composed of colloidal crystal gel, the colloidal crystal gel contains polymer gel that contains ionic liquid and an organic coloring matter, and particles arranged periodically in the polymer gel in a self-organization manner with arrangement of particles being in non-contact filling state. Stop band of the colloidal crystal gel is located in a wavelength region longer than the maximum fluorescent wavelength of fluorescence spectrum of at least the organic coloring matter, and within a range of the fluorescence spectrum.SELECTED DRAWING: Figure 1 |
