Abstract

In this study, we conducted a numerical analysis of LED-pumped solid-state lasers. We developed a simulation model for LED-pumped Nd:KGW and Nd:YAG lasers, incorporating a “five-way” pumping module. The spectral and laser characteristics of Nd:KGW were analyzed. Our results indicate that Nd:KGW crystals may be more suitable for LED pumping compared to the widely used Nd:YAG, as evidenced by their comparative performance. LED pumped Nd:KGW laser showed higher slope efficiency. We provide estimates for the laser output and absorption distribution. The study explores the influence of Nd concentration levels within Nd:KGW on laser outputs when employing LED pumping, while also addressing thermal considerations in Nd:KGW rods.
