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.
