Simultaneous multiple-wavelength cw laser operations were achieved in two types of composite laser rod composed of Nd(3+):YAG and Nd(3+):YLF crystals, which were laser diode (LD) pumped within a single virtual-point-source cavity. As much as 30 W of total output at 1064- and 1047-nm wavelengths was obtained under 150-W LD input power, with approximately 25% from the 1047-nm wavelength. Different bonding methods were compared, showing that the use of an optical adhesive is effective and presents no deterioration at low and middle power levels. Simultaneous multiple-wavelength operation at 1064- and 1053-nm wavelengths was also studied.
在由Nd(3+):YAG和Nd(3+):YLF晶体组成的两种复合激光棒中实现了同时多波长连续波激光运转，这两种复合激光棒在单个虚拟点源腔内由激光二极管（LD）泵浦。在150瓦的LD输入功率下，在1064纳米和1047纳米波长处获得了高达30瓦的总输出，其中约25%来自1047纳米波长。比较了不同的键合方法，结果表明使用光学粘合剂是有效的，并且在中低功率水平下不会出现劣化。还研究了在1064纳米和1053纳米波长处的同时多波长运转。
