摘要

利用所建立的激光二极管二维数值模型，我们研究了腔特性对损耗的影响，并分析了在超高泵浦电流下激光器有效工作的腔参数选择。结果表明，在固定的泵浦电流幅度下，对于最佳腔参数的组合，即腔长度Lopt和输出镜反射率RARopt，实现了最大输出功率。发现通过降低RAR系数来增加功率的可能性是有限的，这是由于在具有高反射率的腔面附近形成了高光学损耗和复合损耗电流的局部区域。

Optimization of Cavity Parameters of High-Power InGaAs/AlGaAs/GaAs Laser Diodes (λ = 1060 nm) for Efficient Operation at Ultrahigh Pulsed Pump Currents

Using the developed 2D numerical model of laser diodes, we study the effect of the cavity characteristics on the loss, and analyze the choice of the cavity parameters for efficient operation of the laser at ultrahigh pump currents. It is shown that at a fixed pump-current amplitude, a maximum output power is achieved for a combination of the optimal cavity parameters, namely, the cavity length L_opt and the output mirror reflectivity R_ARopt. It is found that the possibility of increasing the power by reducing the R_AR coefficient is limited due to the formation of a local region of high optical loss and recombination loss currents near the cavity face with a high reflectivity.
