Buried Depressed-Cladding Waveguides Inscribed in Nd and Yb Doped CLNGG Laser Crystals by Picosecond-Laser Beam Writing.

Buried depressed-cladding waveguides were fabricated in 0.7-at.% Nd:CaLiNbGaO (Nd:CLNGG) and 7.

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.

Incongruent Melting La Y Sc(BO): LYSB Nonlinear Optical Crystal Grown by the Czochralski Method.

Nonlinear optical (NLO) crystals with incongruent melting of La Y Sc (BO) ( x + y + z = 4) (LYSB)-type were grown for the first time, to the best of our knowledge, by the Czochralski method. A special thermal assembly was used and the melt composition, growth direction, and the pulling and rotation rates have been optimized. Good optical quality LYSB crystal with a diameter of about 13 mm and a length of 25 mm has been grown from the LaYSc(BO) starting melt composition, along the c-axis direction, using a slow rotation rate of 8-10 rpm and a high pulling rate of 2 mm/h.
