Crystallography, spectroscopic analysis, and lasing properties of Nd^3+:Ba_2ZnGe_2O_7

Optical properties of the germanate melilites Sr2MgGe2O7, Sr2ZnGe2O7 and Ba2ZnGe2O7

“…Crystal structures While for Sr 2 ZnGe 2 O 7 and Ba 2 ZnGe 2 O 7 structural data can be found in literature [6,10] no structural information of Sr 2 MgGe 2 O 7 , besides X-ray powder diffraction data [2] that signal its membership to the family of melilites, is reported. In the course of our study of optical properties of germanate melilites we analyzed the crystal structure of all three compounds by means of single crystal X-ray diffraction.…”

Tetragonal Ba2MgGe2O7- a novel multifunctional optical crystal with numerous manifestations of nonlinear-laser effects: almost sesqui-octave Stokes and anti-Stokes combs and cascadedχ(3)↔χ(2)lasing with involved second and third harmonic generation

“…However, much less information is found about the growth of large single crystals and physical properties of melilite compounds, especially concerning the germanates. Table 2 [11] were investigated with respect to their spectroscopic properties and laser action [11,42,[97][98][99] , were grown to large single crystals of optical quality using the Czochralski method [100]. These crystals were the basis for electro-optic and piezoelectric investigations of this series of melilites [20].…”

Many-phonon stimulated Raman scattering and related cascaded and cross-cascaded χ(3)-nonlinear optical effects in melilite-type crystal Ca2ZnSi2O7

“…[2][3][4][5][6][7][8]). Special attention in recent years was devoted to studies of various manifestation of cascaded χ (3) ↔ χ (3) and χ (3) ↔ χ (2) interactions in these crystals and to elici- [2,5] SRS, SHG, THG, SFG, self-FD(SRS), self-SRS(FD), ≈ 770, ≈ 257 [12] self-SRS(SRS), St-ASt comb [12] Note: only references from peer-reviewed journals are included. a) Also known as mineral hardystonite (see, e.g.…”
