It is shown, by calculations calibrated against the authors’ recent experimental data, that an eye-safe wavelength range InGaAsP/InP high pulsed power laser design using a bulk active layer, which has a large refractive index step with respect to the optical confinement layer and is located close to the p -cladding, can provide substantial performance improvement compared to the best results achieved so far for this operating regime and wavelength. The dependence of the laser performance on the design parameters such as the thicknesses of the active layer and the waveguide, as well as the cavity length, are analysed. It is shown that the relatively thick bulk active layer in such InGaAsP/InP lasers allows the use of short cavity lengths (∼1 mm or even shorter), for achieving high pulsed power while maintaining a low p -cladding series resistance (making for high efficiency) and a narrow far field (making for high brightness). A single-asymmetry structure with the asy...

非对称波导短腔设计，带有块状有源层，适用于高脉冲功率，对人眼安全的光谱范围激光二极管

通过根据作者最近的实验数据进行校准的计算表明，使用体活性层的人眼安全波长范围InGaAsP / InP高脉冲功率激光器设计相对于光学限制层具有较大的折射率阶跃与迄今在该工作方案和波长下获得的最佳结果相比，它靠近p包层，可以显着改善性能。分析了激光性能对设计参数的依赖，例如有源层和波导的厚度以及腔体长度。结果表明，在此类InGaAsP / InP激光器中，相对较厚的块状有源层允许使用较短的腔体长度（约1 mm或更短），为了实现高脉冲功率，同时保持低的p包层串联电阻（提高效率）和窄的远场（提高亮度）。具有非对称结构的单不对称结构
