An alternative solar pumping approach by a light guide assembly elliptical-cylindrical cavity

Thermal loading effects on Nd:YAG solar-laser performance in end-pumping and side-pumping configurations: a review

“…Several pumping architectures have been proposed for solar-pumped solid-state lasers with the intention of achieving the maximum transfer and absorption efficiencies from the pump source to the laser crystal. 8 These laser systems can have either side-pumping or end-pumping configurations. The most efficient laser systems have endpumping approaches because of the high absorption efficiency of the pump light by the laser crystal.…”

“…6,7 Several pumping architectures have been proposed for solar-pumped solid-state lasers. 8 These lasers can have either side-pumping or end-pumping configurations. Although the most efficient laser systems have end-pumping approaches, the thermal loading effects caused by nonuniform distribution of pump light in these pumping configurations negatively affect their efficiencies.…”

Large Enhancement in TEM00 Solar Laser Power by a Light Guide Assembly-Elliptical Cavity

“…The laser output performance of the proposed pumping approach is analyzed and compared to that of the 2D-DCPC cavity [2]. A plane-plane laser resonant cavity of 450mm length is adopted.…”

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

“…However, the pumping threshold power is simply covered on solar-pumped laser by Fresnel lens [6]. At present, the method of optical fiber is very interesting topic for decreasing the pumping threshold power by tracing deviation [7], but fiber optic transmission loss will not be avoided, which will affect negatively the final collection efficiency of the whole laser system. The product of parabolic reflector efficiency and fiber transmission efficiency is 45% [8], which is lower than 68% of Fresnel lens [3].…”
