摘　　要：报道了使用国产大功率全固态Nd:YAG泵浦组件产生1.3μm附近波长的激光振荡,利用Ⅱ类临界相位匹配的KTP晶体腔内倍频产生高功率的红光激光输出。泵浦组件内包含30个20 W的808 nm二极管阵列,呈三角型阵列分布连续抽运5 mm×125 mm的 Nd:YAG圆棒。为产生高功率的倍频输出,激光器采用V型折叠腔结构,并使用1个声光Q开关。在泵浦功率大约 470 W时,产生了 12 W的准连续高功率红光激光。A high power LD-pumped Nd:YAG/KTP Q-CW red laser was presented. Using a KTP crystal (type I phase-matching, θ = 59.9°, φ = 0°), the red beam was obtained by intracavity frequency-doubling the output wavelengths of Nd: YAG near 1.3 μm. The LD pump module used in this experiment is domestic-made, comprised a φ5 mm × 125 mm Nd:YAG rod side-pumped by thirty 20 W LDs of a triangle radial geometry. For obtaining high power SHG output, we employed a V-folded laser cavity and a acousto-optic Q switch. The highest power of 12 W of Q-CW red laser was obtained with a 470 W pumping power of LD. The curve of power and spectrum of red beam were given in the paper.
