    Abstract: BaTiO3—PbTiO3 series single crystal is single-crystallized by heating BaTiO3—PbTiO3 compact powder member or sintered member having a smaller Pb-containing mol number than Ba-containing mol number, while keeping the powder or substance in non-molten condition. In this way, this single crystal can be manufactured at a crystal growing speed faster still and stabilized more, significantly contributing to improving the dielectric loss and electromechanical coupling coefficient for the provision of excellent BaTiO3—PbTiO3 series single crystal in various properties, as well as for the provision of piezoelectric material having a small ratio of lead content, which is particularly excellent in piezoelectric property and productivity.

    Abstract: A laser oscillator which uses a granular laser gain medium to secure a large gain volume and is capable of suppressing resonator loss caused by granular-boundary scattering. A suspension (1), which is obtained by dispersing a number of dielectric grains doped with a luminous element in fluid having refractive index matched with that of the dielectric grains, is filled in a cell (6). The cell (6) filled with the suspension (1) is disposed in an optical resonator constituted by a rear mirror (3) and an output mirror (4). When the cell (6) is irradiated with excitation light (2), the dielectric grains in the suspension (1) are subjected to laser pumping and a laser beam (5) is output. Since the dielectric grains coexist with the refractive index-matched fluid, the granular-boundary scattering is suppressed, making it possible to provide a low-loss optical resonator. Dielectric grains with a slightly greater diameter may alternatively be distributed in filling liquid which is refractive index-matched fluid.
