高效、纵向二极管泵浦、衍射限制、Nd:YAG 双包层平面波导激光器在 Nd/sup 3+/ 离子的四个跃迁上运行。对于 /spl sim/7 W 的吸收泵浦功率，以及在 1.064 /spl mu/m、946 nm 和 1.3 /spl mu/m 激光波长处的跃迁，分别获得了 4.3、3.5 和 2.7 W 的优化输出功率。弱 /sup 4/F/sub 3/2//spl rarr//sup 4/I/sub 5/2/ 过渡的操作，以 1.833 /spl mu/m 发射激光，在 300 mW 的吸收泵浦功率阈值和 400 mW 的输出功率以及非优化的输出耦合下进行了演示。在引导轴和非引导轴上均获得了衍射限制性能。
An efficient, longitudinally diode-pumped, diffraction-limited, Nd:YAG double-clad planar waveguide laser was operated on four transitions of the Nd/sup 3+/ ion. Optimized output powers of 4.3, 3.5, and 2.7 W were obtained for absorbed pump powers of /spl sim/7 W, for the transitions at the lasing wavelengths of 1.064 /spl mu/m, 946 nm, and 1.3 /spl mu/m, respectively. Operation of the weak /sup 4/F/sub 3/2//spl rarr//sup 4/I/sub 5/2/ transition, lasing at 1.833 /spl mu/m, was demonstrated at an absorbed pump power threshold of 300 mW and an output power of 400 mW, with a nonoptimized output coupling. Diffraction-limited performance was obtained in both the guided and nonguided axes.
