    • There is provided a C12A7 compound capable of selectively and reversibly clathrating X− ions, such as active oxygen radicals, with improved controllability. The C12A7 compound clathrating OH− ions and On− at a concentration of 2×1019 cm−3 or less can be prepared by subjecting a mixed material containing Ca and Al to a solid phase reaction at a firing temperature not lower than 1200° C. and lower than 1449° C. in a dry oxygen atmosphere having an oxygen partial pressure of 0.1 atm or more and a water vapor partial pressure of 10−3 atm or less, keeping the resultant product at a temperature of 1200° C. or higher, and cooling rapidly. The C12A7 compound is heat-treated to clathrate OH− ions at a concentration of 2×1019 cm−3 or less, and On− at a high concentration of more than 2×1019 cm−3. The compound can reversibly clathrate or release On− ion radicals through the elevation or lowering of the temperature thereof in a temperature range of 300 to 850° C. The compound is useful for an oxidation catalyst, an anti-bacterial agent, an ion conducting material, an electrode for a solid-electrolyte fuel cell, and the like.

    • A femtosecond laser radiation or a picosecond laser radiation output from light source 6 is split into a first beam reflected to an angle of 90 degrees by a beam splitter 7 and a straightly advancing second beam cut out by the beam splitter 7. The first beam is reflected at an angle of 90 degrees by a second reflecting mirror 9, reflected again at an angle of 90 degrees by a fourth reflecting mirror 11, and is collimated by a second lens 15 to be irradiated onto an optical fiber core wire 13 to be written. The second beam is reflected at an angle of 90 degrees by a first reflection mirror 8, reflected again at an angle of 90 degrees by a second reflection mirror 10, and is collimated by a first lens 14 to be irradiated onto the optical fiber core wire 13 to be written. The femtosecond laser output from the light source 6 is split into two by the beam splitter 7, which interfere with each other in the vicinity of the core of the optical fiber core wire 13 to generate a change in the refractive indices of the glass depending on the light intensity distribution of the interference fringes, such that the gratings are written in the core 1.
