Diode end-pumped Nd,La:CaNb₂O₆ self-Raman laser with acousto-optic Q-switching was successfully demonstrated for the first Stokes wave generation at 1,174 nm. A 1.0 at.% Nd³⁺ and 1.0 at.% La³⁺-doped CaNb₂O₆ crystal in dimensions 3 × 3 × 14.3 mm³ was used as the self-Raman laser crystal. Doping 1 at.% La³⁺ ions into this crystal could subdue the fluorescence quenching caused by cross-relaxation between Nd³⁺ ions and finally improve the laser output performance. Under the incident pump power of 9.9 W, the first Stokes wave at 1,174 nm with a maximum output power up to 928 mW was obtained, with the diode to Stokes conversion efficiency of about 9.4%. The results show that the Nd,La:CaNb₂O₆ is also a promising self-Raman crystal for efficient fundamental and Raman laser operation.

具有声光调Q的二极管端泵浦Nd,La:CaNb ₂ O ₆自拉曼激光器在1,174 nm处首次产生Stokes波时被成功演示。自拉曼激光晶体使用尺寸为3×3×14.3mm ³的1.0 at.% Nd ³⁺和1.0 at.% La ³⁺掺杂的CaNb ₂ O _6晶体。在该晶体中掺杂1 at.% La ^{3+离子可以抑制Nd 3+}之间的交叉弛豫引起的荧光猝灭。离子，最终提高激光输出性能。在 9.9 W 的入射泵浦功率下，获得了 1174 nm 的第一斯托克斯波，最大输出功率高达 928 mW，二极管到斯托克斯的转换效率约为 9.4%。结果表明，Nd,La:CaNb ₂ O ₆也是一种很有前途的自拉曼晶体，可用于有效的基本和拉曼激光操作。
