摘要： A photoinduced refractive-index changing region is formed by irradiating while focusing a single beam of pulse laser light having an energy amount to cause a photoinduced change in refractive index onto a light guide of an optical element such as a lens, a mirror, a diffraction grating, a polarizer, or a wavelength filter. In the photoinduced refractive-index changing region, since the refractive index is periodically changed in one direction, of the light propagating through the optical element, only a polarized light penetrates through this photoinduced refractive-index changing region. Accordingly, the photoinduced refractive-index changing region can be functioned as a polarizer.

摘要： A single pulse laser beam of linear polarization is irradiated to a glass region such that the condensing point is located inside of the glass region, thereby to form, at the condensing point, a periodic structure region in which high refractive-index zones and low refractive-index zones are repeatedly being generated at pitches of 1 μm or less. Planes in which the high refractive-index zones or the low refractive-index zones are being joined to one another, are formed in parallel to the polarized magnetic field direction of the pulse laser. It is therefore possible to prepare an optical structural body having a submicron-order fine periodic structure which can readily be produced.
摘要翻译：线性极化的单脉冲激光束照射到玻璃区域，使得聚光点位于玻璃区域的内部，从而在聚光点形成高折射率区域和低折射率区域的周期性结构区域指示区域以1um或更小的间距重复产生。高折射率区域或低折射率区域彼此接合的平面与脉冲激光器的偏振磁场方向平行地形成。因此，可以制备具有可以容易地制造的亚微米级周期性结构的光学结构体。

摘要： An inorganic body containing rare earth and/or transition metal ions that has been irradiated with a pulsed laser beam in the manner such that a focal point of the pulsed laser beam is adjusted to an inner part of the inorganic body is disclosed. The inorganic body may be a glass or crystal containing one or more of oxide, halide and chalcogenide. The rare earth ion may be one or more of Ce, Nd, Pr, Sm, Eu, Tb, Dy, Tm, Tb. The transition metal ion may be one or more of Ti, Mn, Cr, V, Fe, Cu, Mo and Ru. When the focal point is relatively shifted with respect to the inorganic body, an ionic valence-changed domain is formed with a predetermined pattern at the inner part of the inorganic body. The pulsed laser beam preferably has a pulse width under a picosecond. The ionic valence change occurs at the focal point and its vicinity, but the rare earth or transition metal ion keeps its original valence at all other parts, so as to form a reformed domain with a predetermined pattern in the inorganic body. Since optical properties are selectively changed at the reformed domain, the processed inorganic body is useful as a functional device such as a memory device or a light-emitting device using the differentiated optical properties.
摘要翻译：公开了一种含有以脉冲激光束的焦点调节为无机体的内部的脉冲激光束照射的稀土元素和/或过渡金属离子的无机体。无机体可以是含有氧化物，卤化物和硫族化物中的一种或多种的玻璃或晶体。稀土离子可以是Ce，Nd，Pr，Sm，Eu，Tb，Dy，Tm，Tb中的一种或多种。过渡金属离子可以是Ti，Mn，Cr，V，Fe，Cu，Mo和Ru中的一种或多种。当焦点相对于无机体相对移动时，在无机体的内部形成具有预定图案的离子价改变域。脉冲激光束优选具有皮秒之下的脉冲宽度。离子价态变化发生在焦点及其附近，但是稀土或过渡金属离子在其他部分保持其初始价态，从而在无机体中形成具有预定图案的重整畴。由于光学特性在改性区域选择性地变化，所以经处理的无机体可用作诸如使用差分光学性质的存储器件或发光器件的功能器件。
