“…Up to now, a large number of research focuses on rare ion-doped CNGG crystals. [12][13][14][15] Nevertheless, only one paper reported the crystal growth and structural properties of Pr:CNGG crystal, [16] but the spectral properties were not mentioned in detail, to the best of our knowledge.…”

Pr3+-doped calcium niobium gallium garnet (Pr:CNGG) single crystals with different Pr3+concentrations are successfully grown by the micro-pulling-down (μ-PD) method. The crystal structure, room-temperature absorption spectra, and fluorescence spectra of Pr:CNGG crystals are measured and discussed. The fluorescence results indicate their large dependence on the doping concentration. The fluorescence lifetime of the D 2 1 energy level is also determined. The results indicate that Pr:CNGG crystal could be a potential solid-state laser gain medium.

“…Laser operation of CNGG crystals was first studied in flash lamp pumped optical cavities when codoped with Cr 3+ (as activator) and Nd, Tm, Ho, or Er . Similarly, laser properties were also found for the isostructural Ca 3 (Ta 1.5 Ga 0.5 )Ga 3 O 12 , CTGG, crystal as well as for Li modifications of the two crystals above, i.e., CLNGG and CLTGG.…”

“…This particular feature broadens all Stark−Stark transitions between 2S+1 L J multiplets of the Ln and induces glass-like optical absorption and fluorescence, which has been well documented in Nd:CNGG single crystals. 5,6 Laser operation of CNGG crystals was first studied in flash lamp pumped optical cavities when codoped with Cr 3+ (as activator) and Nd, 7 Tm, 8 Ho, 9 or Er. 10 Similarly, laser properties were also found for the isostructural Ca 3 (Ta 1.5 Ga 0.5 )-Ga 3 O 12 , CTGG, crystal as well as for Li modifications of the two crystals above, i.e., CLNGG and CLTGG.…”

The Na+-Yb3+ (or Er3+) co-substitution of Ca2+ in Ca3Nb1.5Ga3.5O12 (CNGG) laser crystal is studied. In contrast to other garnets whose structural disorder is exclusively based on the presence of differently sized cations on the same crystal sites, Na+ incorporated in the dodecahedral site (a site also shared by Ca2+ and trivalent lanthanides) creates diverse electric charge distributions over the dodecahedral sublattice, which adds to the disorder associated with Nb5+ and Ga3+ simultaneous occupation of the octahedral and tetrahedral sites. The currently determined cationic compositions of Czochralski grown congruent CNGG and Na-modified CNGG crystals show that Na+ incorporation reduces the cationic vacancy concentration on dodecahedral and octahedral sites but does not affect that in tetrahedral sites. Physical properties of interest for laser design (optical transmission, elastic constants, hardness, specific heat, thermal conductivity, thermal expansion, refractive index dispersion, group velocity dispersion, and thermo optic coefficients) have been systematically determined at cryogenic temperatures and above room temperature. Na+ incorporation into CNGG decreases the crystal growth temperature, promotes Yb3+ doping, and importantly, increases the Yb3+ optical bandwidth, offering good prospects for the implementation of ultrashort pulses in mode-locked laser oscillators.
