AI Technical Summary

Technical Problem

Existing Pr ion-doped oxide laser crystals have low output power when pumped by blue light LDs, are difficult to grow, and have poor thermomechanical properties, which limits their application development.

Method used

Using Pr ion-doped gallium salt laser crystal material, a single crystal material is grown by the Czochralski method with the chemical formula xPr:AB1-xGa3O7, where A is Ca, Sr, and Ba, and B is Y, La, Gd, and Lu. This enhances the absorption and emission intensity of Pr ions, enabling high-power visible light laser output.

Benefits of technology

It achieves high output power visible light laser output under blue LD pumping. The crystal growth is simple, with good physical and chemical stability and thermal properties, and is suitable for cyan, orange and red laser output.
