Provided is a laser oscillation element including a cholesteric liquid crystal layer, in which even in a case where the intensity of excitation light is weak, laser oscillation can be induced. The laser oscillation element includes a cholesteric liquid crystal layer obtained by cholesteric alignment of a liquid crystal compound, in which in a cross-section of the cholesteric liquid crystal layer observed with a scanning electron microscope, bright portions and dark portions derived from the cholesteric liquid crystalline phase are tilted with respect to a main surface of the cholesteric liquid crystal layer, the cholesteric liquid crystal layer includes a colorant that emits light by excitation, and a luminescence wavelength range of the colorant and a selective reflection wavelength range of the cholesteric liquid crystal layer at least partially overlap each other.
