LGYSB:Nd─High-Performance Lasing in the Near-Infrared Region.

Three incongruent melting LaNdGdYSc(BO) (LGYSB:Nd) crystals with different concentrations ( = 0.15, 0.05, and 0.

RE-Doped Ca(Nb,Ga)O and Ca(Li,Nb,Ga)O Crystals (RE = Sm, Dy, and Pr): A Review of Current Achievements.

Spectroscopic characteristics of RE ions (RE = Sm, Dy, and Pr) doped in partially disordered CaNbGaO-CNGG and CaLiNbGaO-CLNGG crystals are reviewed in detail to assess their prospects as laser crystals with emission in the visible spectral domain. All investigated crystals were grown using the Czochralski crystal growth technique. High-resolution absorption and emission measurements at different temperatures, as well as emission dynamics measurements, were performed on the grown crystals.

Efficient 1 µm Laser Emission of Czochralski-Grown Nd:LGSB Single Crystal.

A 5.0-at.% Nd-doped LaGdSc(BO) (Nd:LGSB) borate laser crystal was successfully grown by the Czochralski method, for the first time to our knowledge.

Efficient sensitization of Yb3+ emission by Nd3+ in Y2O3 transparent ceramics and the prospect for high-energy Yb lasers.

Very efficient energy transfer from Nd3+ to Yb3+ in transparent Y2O3 ceramics in the temperature range 10-300 K is demonstrated. It is inferred that this shows potential for the construction of high-energy Yb3+ lasers under diode or flash-lamp excitation of Nd3+.
