A Novelty Analysis Method of Solar-Pumped Laser with Fresnel Lens and Cr/Nd:YAG Ceramic

Abstract:

In this paper, the simple and effective experimental method is proposed for studying on the influence of tracing deviation on solar-pumped laser output performance. The threshold pumping power is obtained by the novelty method. The experimental setup of solar-pumped laser employed Fresnel lens of 1.4×1.05m² and diffuse reflective conical cavity focusing solar radiation on the size of 5mm×60mm Cr/Nd:YAG ceramic. The effective threshold pumping power calculated is 190W, which is about 30% lower than reported results.
