Single crystal of an organic nonlinear optical (NLO) material, Glycine picrate (GP), was grown by slow cooling method. The structural perfection of the grown crystal was analyzed by highresolution X-ray diffraction (rocking curve) measurements. UV-Visible-NIR spectral analysis was used to determine the optical constants and band gap of GP. The nature of variation of dielectric constant with frequency at different temperatures was investigated.Third-order optical nonlinearities of GP crystal were investigated. Etch patterns of the grown crystal quality were studied.

“…Besides crystal growth, J. Bohm et al reported some properties of LGT, LGS and LGN, such as electric conductivity, optical activity, piezoelectric and elastic properties [7,8]. In 2002, J. Stade et al reported electro-optic, piezoelectric and dielectric properties of LGT, LGS and LGN [9], and D. C. Malocha et al measured the LGT thermal coefficients of expansion and density [10].…”

La 3 Ga 5.5 Ta 0.5 O 14 (LGT) crystal was grown by using the Czochralski method. The as-grown crystal is transparent, free from inclusions and with no cracks. Specific heat, thermal expansion, dielectric constants, transmission spectrum and optical damage threshold of LGT have been measured, and the results show general properties of LGT are similar to that of La 3 Ga 5 SiO 14 (LGS) crystal. The experiment to research the Qswitch properties of LGT has been performed and the results show LGT possesses smaller electrooptic coefficients than that of LGS and may not be an ideal material used as a Q-switch.

“…The local symmetry of the sites is D 3 . Besides, there is one site of C 3 [(1/3, 2/3, z), Ga2 tetrahedron] symmetry and two sites of C 2 local symmetry [La (x, 0, 0), Thomson cube and [Ga3 (x, 0, 1/2), trigonal-pyramidal], where x = 0.42492(7) (La), x = 0.7617(1) (Ga3) and z = 0.4689(2) [5,6].…”

Electron paramagnetic resonance and magnetic susceptibility measurements were performed for two La3Ga5.5Ta0.5O14 single crystals doped with 1.96 at.% of Sm 3+ ions and 3.8 at.% of Er 3+ ions. Two magnetically inequivalent sites were found to be responsible for the electron paramagnetic resonance spectra of Sm 3+ ions. Both sites reveal a low (at least C2) symmetry with gx ∼ 0.46, gy ∼ 0.46 and gz ∼ 0.52. The symmetry of isolated erbium ions is higher than C2. From electron paramagnetic resonance and magnetic susceptibility experiments it results that the ground state of Er 3+ ions is Γ 6 or Γ 7 . Below 51 K electronic transitions within Γ 6 doublets take place. Between 51 and 60 K, Γ 6 to Γ 7 transitions dominate, while above 60 K mainly transitions within Γ 7 doublet are active.
