【摘要】文章系统地研究了Er3+:Yb3+共掺磷酸盐玻璃波导的性质,在稳态情况下建立并求解其准三能级系统的速率方程。利用数值分析的方法模拟了980 nm二极管激光器抽运时输出光功率的特性。计算结果表明:经过优化分析,得到了较高的输出光功率和斜率效率,其阈值功率也比较低。更多还原

【Abstract】 The properties of Er3+∶Yb3+ co-doped phosphate glass waveguide pumped by LD are systematically investigated and the rate equations of its quasi-three-energy-level system set up and solved under the steady state.The characteristics of the output power of 980nm laser diode in pumping are analyzed by numerical simulation.The results show that Er3+∶Yb3+ co-doped phosphate waveguide lasers with high fairly high output power and slope efficiency and relatively low threshold power can be achieved on optimized analyses.更多还原
