Abstract
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.
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。
