Abstract

Some glasses such as 15K₂O·15Sm₂O ₃·70P₂O₅ giving the formation of the nonlinear optical KSm(PO₃)₄ phase through the usual crystallization in an electric furnace and through Nd:YAG laser (1064 nm) irradiation have been developed. The crystallization of the KSm(PO ₃)₄ phase showing a second harmonic generation (SHG) is confirmed from X-ray diffraction analysis and micro-Raman scattering spectra. The lines consisting of the KSm(PO₃)₄ phase are constructed by YAG laser irradiation with a power of 0.8 W and a moving speed of 0.5 μms^-1. It is suggested that the crystal growth rate of KSm(PO₃)₄ during laser irradiation is extremely low. The micro-photoluminescence spectra for Sm³⁺ in the crystal lines show the Stark splitting and large intensities compared with the glass part. It is demonstrated that the samarium atom heat processing is effective in the spatially selected crystallization even in phosphate glasses.
