Ferroelastic beta'-(Sm,Gd)_(2)(MoO_(4))_(3) (SGMO) crystal lines are patterned on the surface of Sm_(2)O_(3)-Gd_(2)O_(3)-MoO_(3)-B_(2)O_(3) glasses by continuous wave Yb: YVO_(4) laser irradiations (wavelength is 1080 nm, power is 1.2 W and scanning speed is 5 (mu)m/s). Crystal lines show self-organized periodic domain structures with periodic refractive index changes. The intensity of second harmonic (SH) waves changes periodically depending on the domain structure. It is proposed from polarized micro-Raman scattering spectra and the azimuthal dependence of SH intensities that the orientation of (MoO_(4))~(2-) tetrahedra in SGMO crystals changes gradually and periodically along the crystal line growth direction due to the spontaneous strains in SGMO crystals.
