We investigate the effect of irradiation by a UV pulse laser on the third-order optical nonlinearity of CuCl-microcrystallite-doped glass as a function of the irradiation’s shot number, energy density per pulse, and wavelength. The response time τ

Quenching treatments were performed on CuCl microcrystallite-doped glasses prepared by a melting method. Radiative decay time measurement and χ (3) measurement for the quenched glasses were performed using ps and ns laser. The glasses showed that th

We investigated a microfabrication process for optical gratings with periods of micrometer order that use ultrafast laser pulses in semiconductor-doped glass. ZnS- or PbS-doped SiO2-A12O3-B2O3-CaO-ZnO-Na2O-K2O glass was prepared by a melting method.

We report on photosensitivities in silver ion doped glasses. We succeeded in precipitation control of silver particles without heat treatment by the irradiation of femtosecond laser pulses. The silver particles can be precipitated in a given location

Inelastic neutron scattering experiments on polycrystalline Gd(Fe 11 Ti) and its isostructural nitride Gd(Fe 11 Ti)N 1-δ yield a direct measurement of the exchange field ( B ex ) acting at the unique Gd site in the ThMn 12 -type structure. B ex is 2

Thermally stable highly ytterbium-doped bismuth-oxide-based glasses have been investigated. The absorbance increased linearly with Yb(2)O(3) concentration, reaching 7800 dB/m with 3 mol-% of Yb(2)O(3). An ytterbium-doped bismuth-oxide-based fiber has
