摘要
在本文中，我们用数值方法研究了 LED 发射光谱偏移对 LED 泵浦激光器泵浦特性的影响。我们使用 LED 泵浦 Ce:Nd:YAG 激光器，旨在说明蓝光 LED 发射光谱的变化如何影响泵浦效率。我们提供了因温度变化（从 13 K 到 300 K）而导致的蓝光 LED 光谱变化的吸收分布和效率估算。研究结果表明，即使光谱偏移小至 3-5 nm，吸收效率也会出现高达 5%的负变化。这项研究对于理解 LED 泵浦激光系统并优化其设计以提高效率、稳定性和整体性能具有重要意义。
Influence of LED spectral shift on pumping characteristics in lasers
In the paper, we numerically investigated the effects of the spectral shift in LED emission onthe pumping characteristics of LED-pumped lasers. We aim to illustrate how variations in theblue LED emission spectrum can impact pumping efficiency, using LED pumped Ce:Nd:YAGlaser. We provided estimations of the absorption distribution and efficiency for blue LEDspectral shifts resulting from temperature changes ranging from 13 K to 300 K. Our study demonstratesthat spectral shifts in LED emission affect pumping characteristics. Obtained resultsindicate that even for spectral shifts as small as 3−5 nm, there can be a negative change ofup to 5% in absorption efficiency. This study holds significance in comprehending LEDpumpedlaser systems and optimizing their design to enhance efficiency, stability, and overallperformance.
