“…Zhong et al 62 applied femtosecond laser irradiations (Ti: Sapphire laser, 250 kHz, λ = 800 nm) to grow β’‐GMO crystals on the surface of 21.25Gd 2 O 3 ‐63.75MoO 3 ‐15B 2 O 3 glass. They confirmed the formation of β’‐GMO crystals with a dot shape, but any orientation and also periodic birefringence changes have not been reported.…”

“…Furthermore, it is found that periodic birefringence change did not appear in the specimen obtained in the crystallization of the glass with x = 4 (T g = 530°C, T p = 608°C) ( Figure 17D), demonstrating that stresses in the inside of β-GMO crystals induced by the large density difference between the glassy phase and β-GMO crystal is relaxed effectively in the glasses containing TeO 2 with weak Te-O bonds and fragile character. 48 Zhong et al 62 applied femtosecond laser irradiations (Ti: Sapphire laser, 250 kHz, λ = 800 nm) to grow β'-GMO crystals on the surface of 21.25Gd 2 O 3 -63.75MoO 3 -15B 2 O 3 glass.

Stress-induced crystal axis spiral rotation in multiferroic β'-Gd 2 (MoO 4) 3 crystals observed only in the crystallization of Gd 2 O 3-MoO 3-B 2 O 3 glasses is a new world of glass-crystallization being beyond the usual crystal growth engineering. The selfpowdering phenomenon in crystals synthesized in an electric furnace and the appearance of periodic birefringence images observed in laser-patterned single crystal lines are reviewed together with some new data. Extremely large stresses are created at the interface between super-cooled liquids and crystals due to the density difference between glasses/liquids with larger density and crystals with smaller density, and the crystal axis spiral rotation is induced in β'-Gd 2 (MoO 4) 3 crystals in order to relax and release stresses at the interface. The structural origin of the density difference between glasses and crystals is discussed, and the uniqueness of the crystallization of Gd 2 O 3-MoO 3-B 2 O 3 glasses is emphasized. The possibility of the synthesis of dense bulk glass-ceramics with β'-Gd 2 (MoO 4) 3 crystals is tried using a slow melt-cooling processing.

This paper reports the recent progress in the laser patterning of optical active crystals such as BaAlBO 3 F 2 and ␤-BaB 2 O 4 in glasses. In the laser-induced crystallization using continuous-wave lasers such as Yb:YVO 4 fiber lasers (wavelength: 1080 nm), a steep temperature gradient is created in the laserirradiated region, and highly oriented crystal lines are patterned at the glass surface. The quality and orientation of crystals patterned are characterized from the azimuthal dependence of second harmonic intensities, polarized micro-Raman scattering spectra, and transmission electron microscope observations. Two-dimensional planar crystals with high orientations are patterned by applying laser irradiations with large overlapping. The patterning of crystals in the inside of glass fibers is also possible by moving gradually laser focal point from the surface into the inside. The progress in the crystal patterning with desired morphologies and high orientations provides a high potential for optical active device applications.
