摘　　要：报道了连续激光器二极管 (LD)端面抽运的Nd∶CNGG非均匀加宽激光器。当吸收抽运功率为 6 75 .5mW时 ,最大TEM0 0 模输出功率为 10 5 .5mW、斜率效率为 2 1.2 %、光光转换效率为 15 .6 %。随着抽运功率的增加 ,三个中心波长实现振荡的次序为 10 6 1.3nm、10 5 9.1nm和 10 6 5 .6nm ,实现了三波长同时输出。An inhomogeneously broaden Nd:CNGG laser end-pumped by a CW laser diode was reported. At absorbed pump power of 675.5 mW, the maximum TEM00-mode output power, slope efficiency and optical-to-optical conversion efficiency were 105.5 mW, 21.2% and 15.6% respectively. It was shown that three wavelengths (1061.3 nm, 1059.1 nm and 1065.6 nm) reached thresholds orderly with increase of pump power, and simultaneous three-wave oscillation was obtained eventually.
