摘要

A high-quality disordered Nd ³⁺:Ca ₃Gd ₂(BO ₃) ₄ (Nd ³⁺:CGB) laser crystal was grown by the Czochralski method. The space group and effective segregation coefficient of Nd ³⁺ were determined to be Pnma and 1.06, respectively. The thermal properties, including the average linear thermal expansion coefficient, thermal diffusivity, specific heat, and thermal conductivity were systematically measured for the first time. It was found that the thermal conductivity increases with increasing temperature, indicating glasslike behavior. The polarized spectral properties of the crystal were investigated, including the polarized absorption spectra, polarized fluorescence spectra, and fluorescence decay. The spectroscopic parameters of Nd ³⁺ ions in Nd ³⁺:CGB crystal have been obtained based on Judd-Ofelt theory. The anisotropy of the spectral properties for different polarized directions was discussed. Additionally, the continuous-wave (CW) laser performance at 1.06 μm was demonstrated for the first time. The maximum output power of 603 mW was achieved with corresponding optical conversion efficiency of 8.33% and slope efficiency of 9.95%.
