<p>The optically pumped semiconductor according to the present invention is an optically pumped semiconductor that is a semiconductor of a perovskite oxide. The optically pumped semiconductor has a composition represented by a general formula: BaZr 1-x M x O 3-± , where M denotes at least one element selected from trivalent elements, x denotes a numerical value more than 0 but less than 0.8, and ± denotes an amount of oxygen deficiency that is a numerical value more than 0 but less than 1.5. The optically pumped semiconductor has a crystal system of a cubic, tetragonal, or orthorhombic crystal. When lattice constants of the crystal system are referred to as a, b, and c, provided that a ‰¤ b ‰¤ c, conditions that 0.41727 nm ‰¤ a, b, c ‰¤ 0.42716 nm and a/c ‰¥ 0.98 are satisfied.</p> |
